<span>B. The food supply diminishes in all socioeconmic classes.

It isn't proportional because 3/4 is proportional to 9/16 not 9/15.
In order to know that, you need to divide it from other, if it would be perfect number then your answer will be "YES" & if they not then it will be "NO"
35/100 / 5/100
You can re-write it as:
35/100 * 100/5 = 35/5 = 7
So, they are proportional to each other,.
Hope this helps!
