blanca buys 2 gallons of green paint. she needs 5 quarts to paint her front porch and 1/2 quart to paint the front porch swing. how many quarts of paint does blanca have left

0.625 gallons

Step-by-step explanation:

1 gallon = 4 quarts

2 gallons = 2 × 4 quarts = 8 quarts

She used  = 5 quarts

Usage of paint the front porch swing =  quart = 0.5 quart

used paint = 5 + 0.5 = 5.5 quarts

subtract used paint by starting amount

paint that was not used= 8 quarts - (5.5 quarts) = 2.5 quarts.

used green paint is 2.5 quarts or 0.625 gallons.
