Question

John spent 3 1/4 hours studying. Frank spent 4 7/8 hours studying. Frank spent how many times the amount of hours studying as John?

Answer 1

Frank spent
`(3)/(2)` hours times for studying as John.

Explanation:

Given that,

John spent time in studying =
`3(1)/(4)` hours.

Frank spent time in studying =
`4(7)/(8)` hours.

To find: Frank spent how many times the amount of hours studying as John?

So, Let the frank spent
`x` (in hours) times of hours studying as John.

According to Question,

time taken by Frank for studying =
`x*` time taken by John for studying

`4(7)/(8)=x* 3(1)/(4)`

`(39)/(8)=x* (13)/(4)`

`x=((39)/(8) )/((13)/(4) )=(39)/(8) *(4)/(13)`

`x=(3)/(2)` hours.

Therefore, Frank spent
`(3)/(2)` hours times for studying as John.
