From the question, we are asked to find the solution of 3/4a > -16
3/4a > -16
First let's multiply the reciprocal of 3/4 on each side to get only a on one side of the inequality.
a > -16 * 4/3
We can simplify the above further to:
a > - 64/3
a > -21 1/3
Therefore, the correct option is the first option which is a > -21 1/3.
