This composition is about 250 words in grade three of primary school. The topic is "The Use of Fractional Multiplication". Everyone is welcome to contribute enthusiastically. On Saturday, June 3, 2009, the sun was shining (Mid-Autumn Festival) and math was everywhere. For example: buy food!

Buy stationery!

Measuring cloth, etc. , all need to use mathematics. Today is the Mid-Autumn Festival. My father and I went to the supermarket to buy bananas. It's 1.8 Jin Yuan. My father bought 4.5kg, which should be 8. 1 yuan. But the clerk was careless and didn't know how to calculate it, so it became 9 yuan money. Fortunately, I used my new knowledge of decimal multiplication this semester and did a mental calculation, which immediately corrected my assistant aunt's mistake. The new knowledge taught by the teacher-the multiplication and division of decimals, has helped me a lot!

At this time, my assistant aunt praised me for being smart and being able to do decimal multiplication in such a small city. On the way home, my father praised me for not only saving 0.9 yuan, but also applying what I learned to my life. Yes!

I think: If you don't learn math well, you will lose not only 0.9 yuan, but also hundreds, thousands or even hundreds of millions!

I must learn math well. Serve the motherland when you grow up!
