Answer: C x=-4 and -10
Step-by-step explanation:
.72
.725 would be less because it has more behind the decimal.
.72 would be more because there are only 2 numbers behind the decimal
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!
