Question

The ratios 9:18, 12:24, 15:30, 18:36, and 21:42 form a pattern of equivalent ratios. What is another ratio in the pattern? Please help.

Answer 1

3 : 6

Explanation:

in all the ratios, the first number is multiplied by 2 to get the second number

ex. 9 × 8 = 18 and 15 × 2 = 30

so you can use any two numbers that follow this pattern

my answer : 3 × 2 = 6 so 3 : 6 works in this pattern
