Problem:
A livestock farm has 9/11 tons of feed, and it uses up 4/5 ton. How many tons of feed are left on the farm?
Solution Method
The remaining tons of feed = initial tons of feed − tons of feed used.
Answer
The remaining feed at the livestock farm is:
9/11 - 4/5 = 1/55 (tons)
Answer: 1/55 tons
4. Solution for Exercise 4 - Grade 4 Math Exercise Book 2 Page 40
Problem:
Two water pipes flow into a tank. The first pipe can fill 5/12 of the tank in one hour, and the second pipe can fill 1/3 of the tank in one hour. How many parts of the tank does the first pipe fill more than the second pipe in one hour?
Solution Method
The difference in the amount of water the first pipe fills compared to the second pipe in one hour = the amount of water the first pipe fills in one hour minus the amount of water the second pipe fills in one hour.
Answer
In one hour, the first pipe fills more than the second pipe by:
5/12 - 1/3 = 1/12 (tank)
Answer: 1/12 of the tank
