Perry divided up some candy to give equally to his six friends if c represents the total amount write an expression to represent
Delicious77 [7]
Use easy numbers if you get confused on problems like these.

I'm going to use 12 instead of c.
Since you have 12 pieces of candy and 6 friends, each friend would get 2 pieces, because 12/6=2.

Now, substitute c for 12, and you get c/6.

Hope this helps!
