To make the ratios proportional, the denominator of the second fraction should be the same as the denominator of the first fraction.
In this case, the denominator of the first fraction is 3. Therefore, the denominator of the second fraction should also be 3.
So, the ratio would be proportional if the denominator for 21/3 = 40/3.
What denominator for 21/3=40/? would make these ratios proportional?
