Express your answer in fraction

Answer 1

Trina uses 3.44 or
`( 17.2)/(5)` pints of white paint

Solution:

Given that,

Trina uses 8.6 pints of blue paint and white paint to paint her bedroom walls

3/5 of the amount is blue paint, and the rest is white paint

From given,

3/5 of 8.6 pints is blue paint

`Remaining = 1 - (3)/(5)\\\\Remaining = (2)/(5)`

Thus, 2/5 of 8.6 pints is white paint

How many pints of white paint did she use to paint her bedroom walls?

`White\ paint = (2)/(5) * 8.6\\\\White\ paint = (17.2)/(5)\\\\White\ paint = 3.44`

Thus she uses 3.44 or 17.2/5 pints of white paint
