If 1/3 of a gallon of paint covers 1/9 of a gate, then how many gallons of paint are needed to cover the entire gate?

A. 3 Gallons

B. 20 Gallons

C. 6 Gallons

D. 1 Gallon

3 gallons

Step-by-step explanation:

So just multiply by 9.

You get 3.

3 gallons of paint

Step-by-step explanation:

If 3/4 of a gallon covers 2/5 of a wall, this means that a half of 3/4 gallons can cover 1/5 of a wall.

By knowing this, you can just make up your own expression

(the trick is to find a way to break it down to one, so you can multiply and manipulate it to save yourself some brain cells)

1/5+1/5+1/5+1/5+1/5 = whole wall if 3/4/2=3/8 = amount of paint to cover 1/5 wall, then (3/8) ⋅5=3/8+3/8+3/8+3/8+3/8=15/8≈1.875

since we're talking about real life it would be 2 gallons of paint instead of 1.875 gallons to paint the whole wall
