Answer:
7 1/2
Explanation:
Take it like the following scenario.
There are 7 1/2 M&M's left in a bag.
Neither of your friends want any so you get to have all of them.
So, the 7 1/2 M&M's divided by one person is 7 12 since all of the M&M's go to you.
[Rememember that any number you divide by 1, the answer is itself
Ex: 4 divided by 1 = 4]
I hope this helps!
