Steve uses 8/9 gallon of paint to paint 4 identical birdhouses. how many gallons of paint does he use for each birdhouse?

In a problem like this, we would need to solve for a proportion. But of coarse, we need to set one up.

8/9 gallons of paint for 4 birdhouses.

8/9/4 = x/1

8/9 *1 = 4*x

8/9 = 4x

Divide 4 by both sides.

8/9 ÷ 4 = 4x/4

x = 8/9 ÷ 4

x= 0.22 repeating

Our answer is that for each birdhouse, he use about 0.22 gallons of paint. 

8/9 gallons=4 houses

So to find the amount used for one birdhouse, just divide 8/9 by 4.

8/9

4
=8/9x1/4
=2/9

2/9 gallons of paint are used for each birdhouse.
(2/9 is the same as 0.22 repeating)
