Answer:

A) 1/10

B) 3/40

Explanations:
\text{The number of walls left for Carli to paint = 3}(3)/(4)=(15)/(4)\text{walls}
\text{The amount of paints left = }(3)/(8)\text{gallons}

a) How much paint can she use on each wall in order to have enough to paint the remaining 3 3/4 walls


\text{Amount of paint to use on each wall = }\frac{Amount\text{ of paints left}}{\text{Number of walls}}
\begin{gathered} \text{Amount of paint to use on each wall = }(3)/(8)/(15)/(4) \\ \text{Amount of paint to use on each wall = }(3)/(8)*(4)/(15) \\ \text{Amount of paint to use on each wall = }(1)/(10) \end{gathered}

b) How much paint will be used on the 3/4 of a wall?​

Amount of paint to be used on the 3/4 of a wall = 3/4 x (Amount of paint on a wall)

Amount of paint to be used on the 3/4 of a wall = 3/4 x 1/10

Amount of paint to be used on the 3/4 of a wall = 3/40
