Solution concentration problem

In production and life, we often encounter the problem of solution concentration. This kind of problem mainly studies the relationship among solvent (water or other liquid), solute, solution and concentration. For example, water is a solvent, what is dissolved is called solute, and the mixture after dissolution is called solution. The percentage of solute in a solution is called concentration, also called percentage concentration.

Quantity relation solution = solvent+solute

Concentration = Solute existing solution × 100%

Formulas can be used directly for problems with simple ideas and methods, and formulas can be used after modification for complex problems.

Grandpa 1 has 50g 16% sugar water. (1) How many grams of water should I add to dilute it into 10% sugar water? (2) How many grams of sugar do you need to add to make it 30% sugar water?

How many grams of water does it take to solve (1)? 50× 16% ÷ 10%-50 = 30 (g)

(2) How many grams of sugar do you need? 50×( 1- 16%)÷( 1-30%)-50

= 10 (g)

Answer: (1) needs 30g water, (2) needs 10g sugar.

Example 2 How many grams of 30% sugar water and 15% sugar water do you need to make 600g of 25% sugar water?

The solution is assumed to be all 30% sugar water solution, and the sugar content will be more.

600× (30%-25%) = 30 (g)

This is because 30% sugar water is used too much. Therefore, we assume that a part of 30% solution will be "replaced" by 15% solution under the condition of constant total weight of 600g. In this way, every time you "replace" 100g, the sugar will decrease100x (30%-15%) =15 (g), so you need to "replace" 30% of the solution (that is, "replace"/.

So 200g of 15% solution is needed.

Need 30% solution 600-200 = 400g.

Answer: 200 grams of 15% sugar water solution and 400 grams of 30% sugar water are needed.

The so-called proportional distribution is to divide a number into several parts according to a certain proportion. The known conditions of this kind of questions generally have two forms: one is to reflect the number of parts in the total in the form of ratio or even ratio, and the other is to give the number of parts directly.

From the quantitative relationship of conditions, the ratio of total amount to several parts is known; From the point of view of the problem, find the quantity of several parts. Total number of copies = the sum of the front and back items of the ratio

Ideas and methods to solve the problem: first, convert the ratio of each part into the fraction of the total, add the front and rear terms of the ratio to get the total, then get the fraction of each part (with the total as the denominator and the front and rear terms of the ratio as the numerator respectively), and then calculate the value of each part according to the calculation method of how many fractions there are in a number.

Example 1 According to the number of students, the school assigned 560 trees to three classes in grade five. There are 47 people in Class One, 48 people in Class Two and 45 people in Class Three. How many trees are planted in each class?

The total number of solutions is 47+48+45 = 140.

Tree planting in class 1 is 560× 47/ 140 = 188 (plant)

Tree planting in class two is 560× 48/ 140 = 192 (plant)

Tree planting in class 3 is 560× 45/ 140 = 180 (plant)

Answer: 1 class, class 2 and class 3 planted 188, 192 and 180 respectively.

Example 2 A triangle is surrounded by 60 cm long iron wire, and the ratio of three sides of the triangle is 3: 4: 5. How long are the three sides?

Solution 3+4+5 =1260× 3/12 =15 (cm)

60× 4/12 = 20cm

60× 5/ 12 = 25 cm

A: The lengths of the three sides of the triangle are 15cm, 20cm and 25cm respectively.

Engineering problems

Meaning engineering mainly studies the relationship among workload, work efficiency and working hours. Under the known conditions, this kind of problems often do not give specific quantities, but only put forward "a project", "a piece of land", "a canal" and "a work". The unit "1" is often used to express the total workload when solving problems.

The key to solving engineering problems with quantitative relations is to regard the total workload as "1". In this way, work efficiency is the reciprocal of working hours (it represents a fraction of the total amount of work completed in a unit time), and then formulas can be listed according to the relationship among workload, work efficiency and working hours.

Workload = working efficiency × working hours

Working hours = workload ÷ working efficiency

Working hours = total workload ÷ (A work efficiency +B work efficiency)

The formula of the above quantitative relationship can be used after the ideas and methods of solving problems are revised.

Example 1 a project, it takes 10 days for Team A to do it alone, and 15 days for Team B to do it alone. Now, how many days does it take for two teams to work together?

The "one project" in solving problems is the total amount of work. Because the specific quantity of this project is not given, this project is taken as the unit "1". Because it takes 10 days for Team A to do it alone, it takes110 to complete the project every day; It takes team B 15 days to do it alone, and it takes115 to complete this project every day; If two teams cooperate, the project can be completed every day (110+115).

From this, we can list the formula:1÷ (110+115) =1÷1/6 = 6 (days).

A: It takes six days for two teams to work together.

Example 2 A batch of parts will be completed in 6 hours by Party A and 8 hours by Party B.. Now two people work together to complete the task. A has done 24 more than B. How many parts are there?

If the total workload is 1, Party A will complete 1/6 per hour and Party B will complete 1/8 per hour, and Party A will complete more than Party B (1/6- 1/8). When two people work together, they will complete1. Because it takes [1÷ (1/6+1/8)] hours for two people to work together, during this time, Party A manufactured 24 more parts than Party B, so

(1) How many parts does A make per hour than B?

24 ÷ [1÷ (1/6+1/8)] = 7 (pieces)

(2) How many parts are there in this batch?

7 ÷ (1/6-1/8) =168 (pieces)

A: There are 168 parts in this batch.

Solution 2 The above problem can be calculated in another way:

When two people work together, the workload ratio of Party A and Party B is 1/6: 1/8 = 4: 3.

So Party A finished 4-3/4+3 = 1/7 more than Party B..

Therefore, there are 24 ÷ 1/7 = 168 parts in this batch.

Navigation problem

The problem of sailing is also related to sailing. To solve this kind of problem, it is necessary to understand the ship speed and water speed, that is, the speed of the ship itself, that is, the speed of the ship sailing in still water; Water speed is the speed of water flow, and the speed of sailing along the water is the sum of ship speed and water speed; The speed of sailing against the current is the difference between the speed of the boat and the speed of the water.

Quantity relationship (downstream speed+upstream speed) ÷ 2 = ship speed

(downstream speed-upstream speed) ÷ 2 = water flow speed

Downstream speed = ship speed ×2- current speed = current speed+current speed ×2

Current speed = ship speed ×2- downstream speed = downstream speed-current speed ×2

In most cases, we can directly use the formula of quantitative relationship.

Example 1 It takes 8 hours for a ship to sail 320 kilometers along the river, and the current speed is 15 kilometers per hour. How many hours does it take for the ship to sail against the current?

According to the conditions, the downstream speed = ship speed+water speed = 320 ÷ 8, and the water speed is 15km/h, then the ship speed is 320÷8- 15 = 25(km/h).

The current speed of the ship is 25- 15 = 10 (km).

The time for the ship to travel against the current is 320 ÷ 10 = 32 (hours).

A: It takes 32 hours for this ship to sail against the current.

Example 2 It takes 65,438+08 hours for a ship to travel 360 kilometers upstream, and 65,438+00 hours to return to its original place. It takes 15 hours for ship b to travel the same distance against the current. How long will it take to get back to the original place?

According to the meaning of the question, ship speed+water speed = 360 ÷ 10 = 36.

Ship speed-water speed = 360 ÷ 18 = 20.

It can be seen that (36-20) is equivalent to twice the speed of water,

So the speed of water is (36-20) ÷ 2 = 8 (km) per hour.

Because, B ship speed-water speed = 360 ÷ 15,

So the speed of ship B is 360 ÷ 15+8 = 32 (km).

The downstream speed of ship B is 32+8 = 40 (km).

So it is necessary for ship B to sail 360 kilometers along the river.

360 ÷ 40 = 9 (hours)

A: It will take nine hours for the B ship to return to its original place.

60× 4/12 = 20cm

60× 5/ 12 = 25 cm

A: The lengths of the three sides of the triangle are 15cm, 20cm and 25cm respectively.

Percentage problem

The meaning of percentage is a number, which means that one number is a percentage of another. Percentage is a special kind of score. Scores can often be divided into general scores and reduced scores, while percentages are not needed; Fraction can represent both "rate" and "quantity", and percentage can only represent "rate"; The numerator and denominator of a fraction must be natural numbers, while the numerator of a percentage can be a decimal. The percentage has a special mark "%".

The concept of "percentage point" is often used in practice and practice. One percentage point is 1%, and two percentage points are 2%.

Quantitative relationship Grasp the quantitative relationship among "percentage", "standard quantity" and "comparative quantity";

Percentage = comparison quantity/standard quantity

Standard Quantity = Comparative Quantity/Percentage

There are generally three basic types of ideas and methods to solve problems:

(1) Find what percentage of one number is another;

(2) Given a number, what is it?

(3) Know the percentage of a number and find this number.

1 There is a batch of fertilizer in the warehouse. 720 Jin was used, and 6480 Jin was left. What is the percentage of the original weight used and remaining?

The solution (1) needs 720 ÷ (720+6480) = 10%.

(2) The rest accounts for 6480 ÷ (720+6480) = 90%.

A: 10% was used, leaving 90%.

Hongqi Chemical Plant has 420 male employees and 525 female employees. What is the ratio of male employees to female employees? When solving this problem, the number of female employees is the standard, and the number of male employees is less than that of female employees, so (525-420) ÷ 525 = 0.2 = 20%.

Or 1-420 ÷ 525 = 0.2 = 20%.

A: Male employees are 20% less than female employees.

The problem of composite number

It means that this is a math game and a common math problem in real life. The so-called "composition" is to design a graphic; The so-called "cloth number" is to fill a certain number in the picture. The key to the problem of "composite number" is to meet the given conditions.

The quantitative relationship depends on the requirements of different topics.

The ideas and methods of solving problems are usually considered from the aspects of triangle, square, circle and pentagon. According to the meaning of the title, the number of fabrics is patterned, which meets the conditions given in the title.

Example 1 Ten seedlings should be planted with four trees in five rows. Please do something.

The figure that meets the requirements of the topic should be a five-pointed star.

4×5÷2= 10

Because the five sides of the five-pointed star overlap, you have to subtract half.

Nine seedlings should be planted in ten rows with three trees in each row. Please do something.

The figure that meets the requirements of the topic is two isosceles triangles that cross up and down.

The vertex of one triangle is on the midline of the bottom of another triangle.
