Question

If 3/4 gallon of paint covers 1/3 of the wall then how much paint is needed for entire wall

Answer 1

I believe it would be
`(3)/(4) + (3)/(4)+ (3)/(4)` since you need to cover the wall three times in order to have it fully painted. So the answer should be
`(9)/(4)` which should round up to 3 gallons yes (CharlesTheDillPickle is correct on that).

Answer 2

3/4 times 3
3 times 3 =9
9/4
9 divided by 4 = 2.25
because you have to paint the whole wall you have to have 2.25 so you can't round down therefore you have to round up
so the answer would be
3 gallons
