Question

blanca buys 2 gallons of green paint. She uses 5 quarts to paint her front and 1/2 quart to paint the front porch swing

Answer 1

Paint unused is 0.625 gallons.

Step-by-step explanation:

Quantity of green paint bought = 2 gallons

Now we have to convert gallons to quarts using the conversion factor

1 gallon = 4 quarts

2 gallons = 2 × 4 quarts = 8 quarts

Usage of paint her front = 5 quarts

Usage of paint the front porch swing = $\frac{1}{2}$ quart = 0.5 quart

So used paint = 5 + 0.5 = 5.5 quarts

To find the unused paint, we have to subtract the used quantity from already bought.

Unused paint = 8 quarts - (5.5 quarts) = 2.5 quarts.

So Unused green paint is 2.5 quarts or 0.625 gallons.
