1. First, determine the various parts of the percentage you want to express and their proportions. For example, suppose you want to show the ratio of boys to girls in a class, with boys accounting for 60% and girls accounting for 40%.
2. Draw a circle on the paper and divide it into corresponding sectors. According to the above example, you need to divide the circle into two sectors, one accounting for 60% and the other accounting for 40%, and then draw it.
Percentage refers to the percentage that one number is another number, also known as percentage or percentage. Percentages are usually not written in the form of fractions, but are represented by the symbol "%"(percent sign).
Percent is a special fraction, the denominator is 100 and the numerator is not an integer. Percent indicates that one number is a percentage of another number, indicating a ratio. Percent is a way to express the numerical value of proportion, ratio or fraction, such as 82% for 82%, or 82/ 100, 0.82.
Percentages, also called percentages or percentages, are usually not written in the form of fractions, but expressed by percent signs (%), such as 4 1%, 1% and so on. Because the denominator of the percentage is 100, that is, 1% is the unit, so it is easy to compare. Percent only indicates the relationship between two numbers, so you can't add units after the percent sign.
Percent is a way to express the value of proportion, ratio or fraction, such as 82% for 82%, or 82/ 100, 0.82. Sum and discount represent a few tenths, such as "70%" and "30%", which represent 70/ 100 or 70% or 0.7 respectively. Therefore, the percentage cannot be followed by the unit.
Professor Shi Ningzhong pointed out that the essence of mathematics is to know the relationship between numbers (more and less) at the same time, and further abstract it as "the relationship between numbers (big and small)"
The relationship between two related numbers or quantities can be divided into two categories in primary school: one is the sum-difference relationship of addition and subtraction, and the other is the multiple relationship of multiplication and division. The percentage belongs to the double ratio relationship. Fractions closely related to percentages can exist as a single quantity, or they can represent the relationship between two numbers or quantities.
