Question

You planned to work on a project for about 4 and a 1/2 hours today.

If you have been working on it for 1 and 3/4 hours, how much more time will it take?

Answer 1

`2(3)/(4)`

Explanation:

Given : You planned to work on a project for about 4 and a 1/2 hours today.

To Find :If you have been working on it for 1 and 3/4 hours, how much more time will it take?

Solution:

Total time to be spent on project today =
`4(1)/(2)=(9)/(2) hours`

You have been working on it for hours =
`1(3)/(4)=(7)/(4)`

Remaining time =
`(9)/(2) -(7)/(4)`

=
`(11)/(4)`

=
`2(3)/(4)`

Hence it will take
`2(3)/(4)` hours more .
