Express your answer in fraction

Answer :

Trina uses 3.44 or [tex]\frac{ 17.2}{5}[/tex] 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

[tex]Remaining = 1 - \frac{3}{5}\\\\Remaining = \frac{2}{5}[/tex]

Thus, 2/5 of 8.6 pints is white paint

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

[tex]White\ paint = \frac{2}{5} \times 8.6\\\\White\ paint = \frac{17.2}{5}\\\\White\ paint = 3.44[/tex]

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