Question

This is the math problem that I need help with 15:3=x:5

Answer 1

x =25

Explanation:

Set it up like this

15/3 = x/5 You could cancel or you could cross multiply. We'll do both.

Cancel

15/3 = 5

5 = x/5 Multiply both sides by 5

5*5 = x Combine

25 = x

Cross Multiply

15/3 = x/5 Cross multiply

15 * 5 = 3 * x Combine the left

75 = 3x Divide both sides by 3

75/3 = 3x/3 Do the division

25 = x Answer
