Answer:
A
Explanation:
The reason I would pick A is because it is the reverse of the original equation. In the original, you have two numbers that multiply to be the product, and in answer A the same numbers are used, just in a different order. The way you can check that they have the same value is by taking the end product of the original and dividing it by one of the factors. If the answer is the same as a factor in the original equation it is correct.
For example, if my original equation is 2 * 8 = 16, i could check it by dividing 16 by 8 or 2.
16/8=?
If the answer matches with the factor you left out, then they are the same value.
I hope this helped :)
