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 of paint will be left?

1 gallon is 4 quarts or 8 pints. 9 gallons - 3 gallons = 6 gallons

Then convert it to quarts so, 6*4=24 quarts.

Then subtract that by 10 quarts so, 24-10=14 quarts.

Because you requested the number in pints, you have to convert it again and because there are 2 pints in a quart you multiply it by 2 so, 14*2=28 pints left over.
