Question

If you know that a denominator in your ratio table is 12 and one of

the other ratios is 1/3, what numerator should you apply to your
12 denominator to make that ratio have the same value?

Answer 1

the numerator is 4

Explanation:

1/3 = ?/12

How did the values of the denominator change from 3 in the fraction 1/3 to 12 in the fraction ?/12? 3 was multiplied by 4 to get 12.

Then, since 12 is 4 times 3, then the missing numerator must be 4 times 1.

1/3 = 4/12

Answer: the numerator is 4
