Question

Determine which ratio forms a proportion with 7/2

Answer 1

You should multiply it by the same number such as 14/2 to 7/2. Otherwise, it simply does not work.

Answer 2

For determining proportional ratios, you have to multiply both the denominator and the numerator by the same number

Eg. 14/4 is proportional to 7/2 while 22/6 is not proportional to 7/2.
