Help me out in this question please

The no equivalent answer is C.

Reasoning:
To find the answer you have to multiply 9 x 5/6. Because 9 is a whole number, if we put it over 1 it makes it easier to multiply.

9/1 x 5/6 is 45/6.

Now that we have this, we need to find which answers are correct.

If we change 45/6 into a mixed number, we have to do 45 divided by 6. 45 divided by 6 is 7. 6 x 7= 42. 45-42=3 so the mixed number would be 7 3/6. 3/6 is equal to 1/2 so it can also be 7 1/2. This means A. Is correct.

For the next two multiple choice possible answers, they simplified 45/6. Both have a denominator (bottom of the fraction) of 2. This means we need to divide by a number that will make the denominator 2

45/6 divided by 3/3 will get 15/2. This means B. Is also correct.

Because A and B are correct, this means that C. Is not an equivalent answer.

I hope this helps! If you need any help let me know.
