4 gallons

Step-by-step explanation:

multiply 1/2 by 8 to find the number

Answer 2

Answer:

One gallon of paint can cover $\frac{1}{4}$ of a wall.

Step-by-step explanation:

start by writing the ratio:

$\frac{1}{2\\}$ : $\frac{1}{8}$

There are two halfs in one gallon so you multiply the $\frac{1}{2\\}$ by 2. And whatever you do to one side must be done to the other so:

$\frac{1}{2\\}$×2 : $\frac{1}{8}$×2

Evaluate.

1: $\frac{2}{8}$

this can be further simplified to

1: $\frac{1}{4}$
