Brett has 5/6 of his monthly income left to spend. He has budgeted 1/8 of his income for a new video game and 1/3 of his income
Olenka [21]

Answer:

The only true statement is c. Brett will have 3/8 of his income left after buying the video game and putting money in savings.

Step-by-step explanation:

In order to find this, start by subtracting the fractions of what he'll be spending from the total he has to start.

5/6 - 1/8 - 1/3

Now give them all common denominators

20/24 - 3/24 - 8/24

9/24

Now simplify the fraction.

3/8
