Question

A housepainter mixed 5 gal of blue paint with every 9 gal of yellow paint in order to make a green paint. What is

a ratio of gallons of blue paint to gallons of yellow paint that will make the same shade of green paint?

a. 25:45
b. 15:45
c. 25:27
d. 20.54

Answer 1

A

Explanation:

5:9 is the original ratio.

we know that anything times 5 would have the ones place of either 5 or 0 so we can eliminate c and d. Then we test out the other two choices.

25/5=5

45/9=5

A is correct.

15/5=3

45/9=5

Option B is incorrect.

so, the ratio is 25:45

The answer is A!
