ratelena [41]

Answer:

She used 6.825 pints of withe paint to paint her bedroom walls

Step-by-step explanation:

We know Cathy used 9.1 pints of paint and 1/4 is blue.

first we have to calculate the white paint, we are going to calculate it by subtracting 1/4 of the total paint

1 - 1/4 = 4/4 - 1/4 = 3/4

Now that we know that 3/4 of the total paint is white, we have to multiply it by the amount of paint so we get how many pints of paint are white

3/4 * 9.1 = 6.825

She used 6.825 pints of withe paint to paint her bedroom walls
