Billy stacked six pieces of wood on top of one another. if each piece was 3/4 of a foot tall how tall was his pile

8 feet is the answer

The way that I would do this is to put 6 into an improper fraction with the same common denominator as 3/4. That would end up coming to 24/4. You multiply both the numerator and the denominator straight across which would come to 72/16. Then, to simplify that all you have to do is divide 72 by 16. That should come out to 4.5. Hope this helped! :)

Iam guessing c. or d.
