Question

if 1/2 of a gallon of paint covered 1/4 of the wall how much does it take to cover the whole wall???

Answer 1

2 gallons

Explanation:

If you use one whole gallon, you will have covered 2/4.

When you simplify this fraction, you get 1/2. This means you have another half to cover.

So, 1 gallon plus another gallon is 2.

Answer 2

2 gallons of paint.

Explanation:

Since
`(1)/(2)` gallon of paint covered =
`(1)/(4)` of the wall.

Therefore, 1 gallon of paint covered = 1 ×
`(1)/(4)` =
`(2)/(4)` =
`(1)/(2)` of the wall.

To paint 1 wall we need the paint =
`(1)/((1)/(2) )` =
`1*(2)/(1)` gallon of paints

= 2 gallons of paint.

2 gallons of paint covers the whole wall.
