Question

Henry wants to make a green paint. The ratio of yellow to blue paint is 3 to 5. If he has 25 parts blue, how many parts of yellow does he need?

Answer 1

Answer:

15

Step-by-step explanation:

If the ratio is 3:5, then if you multiply one number (5 in this case) you also have to multiply the other for it to make sense. If you multiply 5 by 5, you also have to multiply 3 by 5, which gets you your answer.
