Answer:
A) 1/10
B) 3/40
Explanations:[tex]\text{The number of walls left for Carli to paint = 3}\frac{3}{4}=\frac{15}{4}\text{walls}[/tex][tex]\text{The amount of paints left = }\frac{3}{8}\text{gallons}[/tex]
a) How much paint can she use on each wall in order to have enough to paint the remaining 3 3/4 walls
[tex]\text{Amount of paint to use on each wall = }\frac{Amount\text{ of paints left}}{\text{Number of walls}}[/tex][tex]\begin{gathered} \text{Amount of paint to use on each wall = }\frac{3}{8}\div\frac{15}{4} \\ \text{Amount of paint to use on each wall = }\frac{3}{8}\times\frac{4}{15} \\ \text{Amount of paint to use on each wall = }\frac{1}{10} \end{gathered}[/tex]
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
