Question

Work out the values of A and B in these equivalent ratios.
A: 8:5
9:24: B

Answer 1

A=3

B=15

Explanation:

Since these are equivalent ratios, there is a constant scale factor for each number. As shown in the 8 and 24, we find the scale factor to be 24/8=3. This means that the second ratio's numbers are 3x bigger than the corresponding ones in the first ratio. A = 9/3 = 3, and B = 5*3=15
