Question

Sonia studied for 2 1/3 hours for the math test james studied 3/4 as long as sonia how many more hours did sonia study than james

Answer 1

`1(3)/(4) \ hours` more Sonia study than James.

Explanation:

Given:

Sonia studied for 2 1/3 hours for the math test james studied 3/4 as long as Sonia.

Now, to find hours more Sonia study than james.

Sonia studied =
`(7)/(3) \ hours.`

James studied =
`(3)/(4) \ hour.`

Now, to get the more hours Sonia study than James we subtract the hour James studied from hours Sonia studied:

`(7)/(3) -(3)/(4)`

`=(28-9)/(12)`

`=(21)/(12)`

`=(7)/(4)`

`=1(3)/(4)\ hours.`

Therefore,
`1(3)/(4) \ hours` more Sonia study than James.
