Question

The ratio of two numbers is 3:7. If the larger number is 35, what is the smaller number

Answer 1

The smaller number is 15

Explanation:

To find this, set up a proportion where the ratio is a fraction and the new value is with x on the other side.

3/7 = x/35

Now cross multiply to solve.

35 * 3 = 7 * x

105 = 7x

15 = x
