Question:

Martin uses 5/8 of a gallon of paint to cover 4/5 of a wall. what is the unit rate at which Martian paints in walls per gallon

Answer:

0.78125  walls per gallon

Step-by-step explanation:

Given

[tex]Paint = \frac{5}{8}\ gallon[/tex]

[tex]Wall = \frac{4}{5}[/tex]

Required

Determine the unit rate

This is calculated as:

[tex]Unit\ Rate = \frac{Wall}{Paint}[/tex]

Substitute values for wall and paint

[tex]Unit\ Rate = \frac{5/8}{4/5}[/tex]

Simplify:

[tex]Unit\ Rate = \frac{5}{8}/\frac{4}{5}[/tex]

Change to *

[tex]Unit\ Rate = \frac{5}{8}*\frac{5}{4}[/tex]

[tex]Unit\ Rate = \frac{5*5}{8*4}[/tex]

[tex]Unit\ Rate = \frac{25}{32}[/tex]

[tex]Unit\ Rate = 0.78125[/tex]

Hence, the unit rate is: 0.78125  walls per gallon
