Question

Kelly uses 7.4 pints of white paint and blue paint to paint her bedroom walls. 1 4 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?

Answer 1

5.5 pints of blue paint she use to paint her bedroom walls.

Explanation:

Given:

Kelly uses 7.4 pints of white paint and blue paint to paint her bedroom walls.

1/4 of this amount is white paint, and the rest is blue paint.

Now, to find the pints of blue paint she use to paint her bedroom walls.

Total pints of white paint and blue paint = 7.4 pints.

`(1)/(4)` of this amount is white paint.

So, first we need to find the pints of white paint:

`(1)/(4)\ of\ 7.4\\\\=(1)/(4) * 7.4\\\\=1.85\ pints.`

Thus, the amount of white paint is 1.85 pints.

Now, to get the pints of blue paint we subtract the pints of white paint from the total amount of white paint and blue paint:

`7.4\ -\ 1.85\\\\=5.55\ pints.`

Therefore, 5.5 pints of blue paint she use to paint her bedroom walls.

Answer 2

5.55 pints of blue paint has been used by Kelly to paint her bedroom walls

Explanation:

• The total amount of white and blue paint available to Kelly to paint her entire bedroom is 7.4 pints.
• The amount of white paint of the total amount of paint is 1/4th.Therefore, the total amount of white paint used by Kelly=
  `(1)/(4)* 7.4`=1.85 pints.
• Hence, the total amount of blue paints used by Kelly to paint her bedroom=
  `(7.4-1.85)=5.55`.
• Therefore, the amount of blue paint used by Kelly to paint her entire bedroom walls is 5.55 pints.
