Abby uses 7.7 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?

Well, isn't that a happy little math problem we have here! Abby used 7.7 pints of paint in total, with 3/5 of that being white paint. To find out how many pints of blue paint she used, we can first calculate how much white paint she used (7.7 pints x 3/5 = 4.62 pints of white paint). Then, we can subtract the amount of white paint from the total to find the amount of blue paint she used (7.7 pints - 4.62 pints = 3.08 pints of blue paint). Happy painting!
