Question

Dean is painting a fence. If 3/4 gallon of paint can cover 1/8 of the fence,how many gallons will he need to paint the whole fence?

Answer 1

He will need 6 gallons to paint the whole fence

Explanation:

To know the number of gallons that will be needed to paint the whole fences, we will follow the step below;

let x be the number of gallons that he will need to paint the whole fence

We can use proportion to solve the problem

3/4 gallon = 1/8 fence

x gallon = 1 fence

cross-multiply

3/4 × 1 = 1/8 × x

`(3)/(4)` =
`(X)/(8)`

CROSS-MULTIPLY

4 × x = 3 × 8

4x = 24

divide both-side of the equation by 4

4x/4 = 24/4

x =6

Therefore,he will need 6 gallons to paint the whole fence
