To make the ratios proportional, we need to find a common denominator for both fractions.
The denominator for 21/3 is 3, and the denominator for 49/7 is 7.
Now we need to find the least common multiple (LCM) of 3 and 7, which is simply the product of the two numbers, since they are prime.
The LCM of 3 and 7 is 3 * 7 = 21.
Therefore, a denominator of 21 would make the ratios proportional.
