Final answer:
The solution set of the equation '3 over 4 of a number is 24' is {32}.
Step-by-step explanation:
To solve for 12, we have to do some algebraic rearrangement: divide 24 by 3/4. To divide by a fraction, we multiply by its reciprocal, which in this case is 4/3. So, 24 multiplied by 4/3 equals 32. Therefore, the solution set of the equation is {32}.
