Question

Pearl uses 9.8 pints of blue paint and white paint to paint her bedroom walls. 2 5 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?

Answer 1

Answer:

She use 5.88 pints of white paint.

Step-by-step explanation:

Given:

Pearl uses 9.8 pints of blue paint and white paint to paint her bedroom walls. $\frac{2}{5}$ of this amount is blue paint, and the rest is white paint.

Now, to find the pints of white paint she use.

Pearl uses total pint of paint = 9.8 pints.

The amount of blue paint

= $\frac{2}{5}\ of\ 9.8\ pints.$

= $\frac{2}{5} \times 9.8$

= $\frac{19.6}{5}$

= $3.92\ pints.$

Thus, the amount of blue paint = 3.92 pints.

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

$9.8-3.92\\\\=5.88\ pints.$

Therefore, she use 5.88 pints of white paint.
