Question

If Tucson's average rainfall is 12 1/4 and Yumas is 2 3/5 inches, how much more rain, on an average does Tucson get? ...?

Answer 1

`9(13)/(20)\text{ inches}`

Explanation:

Given,

Tucson's average rainfall =
`12(1)/(4)\text{ inches}=(49)/(4)\text{ inches}`

Also, Yumas's average rainfall =
`2(3)/(5)\text{ inches}=(13)/(5)\text{ inches}`

Difference between Tucson's average rainfall and Yumas's average rainfall

`=(49)/(4)-(13)/(5)`

`=(245-52)/(20)`

`=(193)/(20)`

`=9(13)/(20)`

Hence, Tucson gets
`9(13)/(20)` inches more rainfall.

Answer 2

9 13/20 inches more, through subtracting the fractions to have the same denominator
