Answer:
16
Explanation:
Let's start by working backwards.
you subtract 16 from 28 since subtracting by a negative makes you add and we want to do the inverse of that.
28-16=12
then since 12 is equal to 3/4 of a certain number, that means we have to divide that number by 3/4
12/(3/4)=16
our answer is 16
