Question

If Tucson’s average rainfall is 10 1/4 inches and Yuma’s is 4 4/5 inches, how much more rain, on the average, does Tucson get than Yuma?

Answer 1

`5 (9)/(20)`

Explanation:

If Tucson’s average rainfall is 10 1/4 inches and Yuma’s is 4 4/5 inches, then the difference will give us how much more rain, on the average,Tucson get than Yuma.

`10 (1)/(4) - 4 (4)/(5)`

`= (41)/(4) - (24)/(5)`

We find LCM to get

`(205 - 96)/(20)`

`(109)/(20) = 5(9)/(20)`
