Question

Jared is scheduled to work for 5/6 of an hour at the school fair. He has already worked 1/3 of an hour. How much longer does he have to work. A.1/3 h B.5/6 h C.1 h D 1/2 h

Answer 1

The answer is D

Because
5/6 - 1/3
=5/6 - 2/6
=3/6
=1/2h

Answer 2

D 1/2 h

Explanation:

To find how much more time Jared has to work, you must take the total time he must work and subtract the time he has already worked.

`(5)/(6)-(1)/(3)`

1. First take out the common denominator:

`(5)/(6)-(1)/(3)=(5-2)/(6)`

2. Then make the operations:

`(5)/(6)-(1)/(3)=(3)/(6)`

3. Finally simplify the expression:

`(5)/(6)-(1)/(3)=(1)/(2)`

Therefore Jared needs to work
`(1)/(2)` hour to end his shift.
