Question

I JUST NEED THE EQUATION

Lisa won 51 pieces of gum playing hoops at her school's game night. Later, she gave three to each of her friends. she only has 9 remaining. How many friends does she have?

(this question killed me)

Answer 1

14 friends. Take 51 and subtract 9. what you have left, divide by 3.

Answer 2

51-9= 42
42/3= 14
your answer would be 14 friends
CHECK:
3*14= 42
