Question

Keiko uses 8.7 pints of white paint and blue paint to paint her bedroom walls. 3 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

3.48 pints

Explanation:

Given

Fraction of white paint = 3/5

Total pints of paint used = 8.7

Amount of white paint used = 3/5 * 8.7 = 5.22 pints of white paint

Amount of blue paint used :

(8.7 - 5.22) pints = 3.48 pints

Hence, 3.48 pints of blue paint was used.
