When I arrived at the shopping mall, I saw two kinds of noodles for me to choose from, one was 450g, and the other was 400g, which was 2/3 of the price of the first kind of noodles, 4.5÷3= 1.5 (yuan), 1.5×2=3 (yuan), and I ate it alone at home. It suddenly occurred to me that my mother asked me to buy five shuttlecocks at two yuan each, 5×2= 10 (yuan), 10+3= 13 (yuan) and 30- 13 = 17 (yuan).
Return home,10; In 20 minutes, I prepared two eggs first, and then I watched TV.
Time flies to 12: 00, so I quickly beat eggs. After 20 minutes, a bowl of steaming noodles is ready. I wolfed down my noodles and then went to bed for a nap.
I took a nap and woke up at four. My parents will be back in two hours. I’m not doing anything right now. Suddenly I saw a pile of unwashed clothes. I immediately rushed over and started washing clothes.
It takes me five minutes to wash a dress, and one * * * gets eight clothes. I divided eight clothes into two piles, 8÷2=4 (pieces), and each pile contained four clothes. It takes me 8 * * * 5 = 40 minutes to finish washing clothes, so I have no choice but to bite the bullet and wash it.
It's 5 o'clock after washing clothes, 40 minutes after washing clothes, and more than ten minutes after waking up. My parents came back early, saw what I did and praised my ability!
The experience of "being the master of my own house" was so interesting that it enhanced my self-reliance. Although some simple math problems, but also let me know how to use math knowledge to better manage my parents' finances.
