Correct question:

Joanie uses 6.4 pints of blue paint and white paint to paint her bedroom walls. ³/₄ of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?

The quantity of white paint she used to paint her bedroom walls is 1.6 pints

Step-by-step explanation:

Given;

total quantity of  blue paint and white paint used by Joanie = 6.4 pints

she uses ³/₄ of the total quantity of the paints as blue

the remaining fraction as white paint = 1 -  ³/₄ = ¹/₄

The fraction of the total quantity of paints that is white paint = ¹/₄

And,

The quantity of white paint she used to paint her bedroom walls = ¹/₄  x 6.4 pints = 1.6 pints

Then, quantity of blue paint she used = ³/₄ x 6.4 = 4.8 pints

Check:

blue paint + white pain = total

4.8 + 1.6 = 6.4 pints

Therefore, the quantity of white paint she used to paint her bedroom walls is 1.6 pints
