Today is Saturday. I am at home alone. I woke up at half past eight. I jumped out of bed at once. At this moment, my mother called and told me something. It took me five minutes to answer this call. I quickly changed my clothes, brushed my teeth and washed my face. Then go straight to the table for breakfast. Fifteen minutes later, 15+5=20 (minutes), 8: 30+20 = 8: 50 (minutes), 12: 00-8: 50 = 3: 50 (minutes), and it will be noon in three hours and fifty minutes. At this time, I found that there were no noodles, so I took 30 yuan to go to Xinli Shopping Mall to buy noodles.

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.
