Question

Andrea uses 8.1 pints of white paint and blue paint to paint her bedroom walls.

4/5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls

Answer 1

2.025 pints of blue paint

Explanation:

4/5 = 80/100 or 80%

8.1 is 80% of 10.125

10.125 is the total pints of paint used.

If 8.1 of those pints of paint are white, then the rest of the paint must be blue.

10.125 - 8.1 = 2.025
