Jane uses 8.4 pints of blue paint and white paint to paint her bedroom walls. 4/5 of the amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?

1.68 pints

Step-by-step explanation:

First you need to determine how much blue paint she used, then you can determine how much white paint she used. :)

4/5 of 8.4:

4/5 * 8.4 = 6.72 pints

Now we can determine how many pints of white paint she used by subtracting 6.72 from 8.4:

8.4 - 6.72 = 1.68

So she used 1.68 pints of white paint. :) Hope this helped!
