Question

Tyler used 1 1/4 gallons of paint to paint 5/8 of a fence. How many gallons will it take to paint the whole fence?

Answer 1

2 gallons

Explanation:

1 1/4 = 1 + 1/4 = 4/4 + 1/4 = 5/4

Then:

5/4 gallons ⇒ 5/8 fence

x gallons ⇒ 8/8 fence

x = (5/4)(8/8) / (5/8)

x = ((5*8)/(4*8)) / (5/8)

x = (5/4) / (5/8)

x = (5*8)/(4*5)

x = 40/20

x = 2
