Melanie uses 8.8 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?

1 answer

white: 4/5 * 8.8 = 0.8 * 8.8 = 7.04 pints
blue: 8.8 - 7.04 = 1.76 pints

not so hard after all, was it?
