In the sixth grade, 100, there is an answer in the calculation process of mathematical formula. If you encounter a problem that you can't, you will find the answer online and copy it down. You don't want to think at all, it will make students develop, and you can't ask the answer online.
The habit of not thinking, correct it, think more about doing problems, and be afraid of not thinking.

Uncle Gao is better than Uncle Zhou =4 to 6.
Uncle Gao: 5/(4+6) * 4 = 20,000 yuan.
Uncle Zhou: 5/(4 = 6) * 6 = 30,000 yuan.
From 12 to 24: 00, the clock made a circle. The minute hand went 12 turn.
Spring area =π*4*4
Walking area of minute hand =π*5*5* 12
=300π
16π/300π* 100%=5.3%
The area swept by the hour hand is 5.3% of the area swept by the minute hand.
