Larry has 9 gallons of paint. He uses 10 quarts to paint his kitchen and 3 gallons to paint his living room. How many pints will be left?

28 pints

Step-by-step explanation:

There are 4 quarts in a gallon

There are 2 pints in a quart

We know 10 guarts = 10/4 = 2.5 gallons = 2 gallons 2 guarts

Subtracting the 10 quarts in the kitchen

9 gallons - 2 gallons 2 quarts

Changing 1 gallon to 4 quarts

8 gallons 4 quarts - 2 gallons 2 quarts = 6 gallons 2 quarts

Then he used 3 gallons in the living room

6 gallons 2 quarts - 3 gallons = 3 gallons 2 quarts

Changing gallons to quarts

3*4 = 12 12 quarts + 2 quarts = 14 quarts

Now we need to change to pints

14 quarts * 2 pints = 28 pints

Answer: 28
