It takes 32 people to build 8 houses. How many people would it take to build 20 houses? (hint simplify your ratio first)

So, we know the ratio is 32:8

8 is a factor of 32, so we can divide both sides by 8:

The new ratio is 4:1

This means that it takes 4 people to build one house.

To satisfy the needs of the question, let's multiply both sides by 20:

80:20

It will take 80 people to build 20 houses.

It would take 80 people to build 20 houses because you you divide 32 by 8 and get 4 and then multiply by 20 to get 80
