Today, my family went to KFC in Longgang for a family meal.

When we get there, people are always crowded. We finally ordered good food and found a seat to sit down. Here comes the food. This is a sumptuous set meal. There are 12 drumsticks in it. I thought: how to divide it equally? Then I remembered the division of 12÷3=4. We each have four drumsticks. Later, I ate my mother's 1 chicken leg and my aunt's two chicken legs. My aunt said, "You can't eat this for free. I ask you, how much did you eat? " How many more servings do you have to eat before you can finish them all? "I thought about it and replied," I ate 7/ 12, and then I ate 5/ 12. I ate all of it. "Fortunately, I learned the knowledge of fractions and can answer the questions correctly.

Today, my mother gave me 10 yuan to go shopping in the supermarket. I bought a string of firecrackers 2/ 10, four lollipops/10, seven balloons 2/ 10, and finally a comb 4/ 10, a *. There is still one yuan left, and I have to pay it back to my mother.

When I got home, my mother ate 1/4 lollipop, and my father ate 1/4 lollipop.

I ate 1/4 lollipop, and there is one left. I gave it to the Xiao Qiang brothers next door. (Author: Xiao Enling)

Last week, we studied fractions. Fractions have numerator, denominator and fractional line, for example, 1/3, where 3 is denominator, 1 is numerator and the middle horizontal line is fractional line.

Scores are used in many places in life. For example, a book has thirty pages, and each page is 1/30 of a book. Fractions can also be used to add and subtract! For example, half plus half equals two, which is 1. Why is this happening? If you divide a cake into two parts, each part is 1/2 of the cake, and then put the two parts together, there are two parts 1/2, which is just a cake. When adding and subtracting fractions, if the denominator is the same, only the numerator is added, regardless of the denominator. And 2/2 of the numerator and denominator are the same, which is 1.

I also learned to compare the size of fractions. The teacher taught us the formula: numerator is the same as denominator, the fraction with large denominator is small, and the fraction with small denominator is large; Denominators are the same as numerators, with large numerator scores larger and small numerator scores smaller.

The teacher also reminded us that when writing scores, we usually write the fractional line first, indicating the average score, then the denominator and finally the numerator.

Today, my mother and I went to the bookstore to read books. Mom said, if you have good books, buy them, but if you don't have good books, read them.

Mom has read six books, with an average of 12 yuan. I read 18 books, which is three times that of my mother, but each book is only 6 yuan on average, so the price of each book my mother reads is twice as high as mine.

Mom saved 72 yuan, I saved 108 yuan, and we both saved 180 yuan. Ah, what a savings!

Do you know what volume is? I don't think you know, let me tell you! Volume is: the size of the space occupied by an object is called the volume of the object. The unit of volume is usually: cubic meter, cubic centimeter, cubic decimeter, expressed in letters: m, cm, DM.

How big is 1 cubic centimeter? In our daily life, many objects are 1 cubic centimeter, such as dice, cubes and so on. To be precise, the volume of a small cube with a length of 1 cm is 1 cm. How big is 1 cubic decimeter? 1 cubic decimeter is a cube with a side length of 1 decimeter. In daily life, there are many things 1 cubic decimeter, such as chalk boxes and Rubik's cubes. How big is 1 m3? The volume of a cube with a side length of 1 m is 1 m3. The box and cabinet of TV set in life is about 1 m3.

There are still many mysteries about volume, waiting for us to discover and explore.
