Staci has 8 3/8 liters of paint and uses 5 3/4 liters of it. How much paint does Staci have left? Give your answer in simplest form.

We will use subtraction to solve this. We will subtract 5 3/4 from 8 3/8, because we must take away the amount she used.

8 3/8 - 5 3/4

The easiest way to solve this is to convert to fractions.

67/8 - 23/4

We must create common denominators to solve this. We will multiply both 23 and 4 from the second fraction by 2 to get to a common denominator of 8.

67/8 - 46/8 = 21/8

We will then convert this fraction back to a mixed number.

21/8 = 2 5/8

2 5/8 liters is our final answer
