Factors of 121 are; 1,11, and 121. so it would be D.
Answer: What you would have left is 12 pieces of pie
Step-by-step explanation: As stated in the question, one pie has been sliced into 8 pieces, and there are three pies in all. That means we had at the beginning 3 x 8 slices of pie which equals 24 pieces.
Also if each pie had been sliced into 8 pieces then each can be represented as 8/8. Therefore eating one slice would leave you with 7/8 (that is 8/8 minus 1/8).
So, each of the three pies now have the following left overs;
1/2, 3/8 and 5/8.
Adding them all together would give,
1/2 + 3/8 + 5/8
Using 8 as the common denominator
4/8 + 3/8 + 5/8
(4 + 3 + 5)/8
12/8.
Therefore, there would be 12 pieces left altogether, which can also be expressed as one pie and 4 pieces.
