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

sess of a gallon of paint to cover for a man who

1 walls per gallon

of a wall per gallon

15 walls per gallon

walls per gallon

martin paints at a unit rate of 1.6 gallons per wall ( that means 1.6 gallons are used to paint 1 wall) or 0.625 wall per gallon (that means 0.625 wall is painted by 1 gallon)

Step-by-step explanation:

5 walls = 8 gallons

1 wall = 8/5 gallons  ( we divided both sides by 5 since we want to know how many gallons would be needed for 1 wall)

1 wall = 1.6 gallons

if we are to calculate gallon per wall, it would be

8 gallons = 5 walls

1 gallon = (5/8) walls

1 gallon paints 0.625 wall

to calculate for 15 walls knowing the rate of gallons per wall

so if 1 wall = 1.6 gallons

then 15 walls = 1.6 * 15 = 24 gallons

similarly, using walls per gallon (this is a longer method)

0.625  walls = 1 gallon

0.625 = 5/8 walls ( so what do we multiply with this figure to give us 15 walls?)

15 / (5/8)

(15 *8)/5 = 3*8 = 24 gallons

so 15 walls would need 24 gallons

clear ? if not please let me know

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
