Question

Answer 1

24 is your answer

Explanation:

18 : x = 9 : 12

You are solving for x. First, simplify the ratio on the right side.

(9/3) : (12/3) = 3 : 4

Next, solve for x. Multiply. Remember that what you do to the numerator, you do to the denominator.

3 : 4 = 18 : x

3 (6) : 4 (6) = 18 : x

Simplify

18 : 24 = 18 : x

x = 24

Answer 2

24

Explanation:

We want the ratios to be equal

18:x 9:12

18 9

--------- = -----------

x 12

We divide by 2 to get from 18 to 9

x ÷2 =12

Multiply each side by 2

x ÷2*2 =12*2

x = 24

18:24 9:12
