Sasha uses 6.1 pints of white paint and blue paint to paint her bedroom walls. 2/5 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?

3.66 pints of blue paint.

Step-by-step explanation:

She used 2/5 of the total number of pints to paint white.

That number in pints is:

= 2/5 * 6.1

= 2.44 pints of white

The number of pints used to paint blue is therefore:

= 6.1 - 2.44

= 3.66 pints of blue paint.
