Mathematical application problem 1. Peanut oil yield is 25%. How many kilograms of oil can be extracted from 400 kilograms of peanuts? How many peanuts does it take to squeeze 400 kilograms of oil?
1, 400×25%= 100 kg,

400/25% =1600kg

Answer: 400 kg of peanuts can squeeze out 100 kg of oil, and it takes 1600 kg of peanuts to squeeze out 400 kg of oil.

2,9 (2/7-1/5) =105 kg

A: The supply of this batch of fruit is 105 kg.
