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.

Learning math well can save money.

On Sunday, my parents and I went to the supermarket to buy toothpaste. We found that there are two ways to sell the same kind of bamboo salt toothpaste: 1, three pieces110g toothpaste, fresh and pleasant package 17.9 yuan; 2. A toothpaste 8 yuan with a weight of 150g. Which of these two ways do you think saves money? "Now I'm stumped. My mother said to me," Today, let's put 17.9 yuan pawn 18 yuan. Do the math! " I immediately said, "Save money by buying fresh and enjoyable clothes." Mother asked, "Why? "I said I thought so: three boxes 18 yuan, each box of toothpaste 6 yuan 18 ÷ 3 = 6 (yuan). 150g toothpaste per box of 8 yuan, that is, more 2 yuan money to buy 40g toothpaste, so 1 yuan can buy 20g toothpaste. And if you buy 150g toothpaste, 1 yuan can't buy 20g. So I think buying fresh and pleasant clothes saves money! Hearing this, my mother said to me happily, "Great! Learning math well is really useful! "
