Joseph had 7 1/4 ounces of candy to share with his friends. He gave them 2 4/5 ounces of candy when they came over to play video games. How many ounces of candy does Joseph have left? Explain.

4 9/20
make sure you have the same denominator.
this is a subtraction problem.
7 1/4 turns into 7 5/20 and 2 4/5 turns into 2 16/20. since you can not subtract 16/20 from 5/20 you need to borrow from the whole which is 7. so 7 becomes a 6 and you add 20/20 +5/20 and get 25/20 now you can subtract 6 25/20  2 16/20 = 4 9/20 
did this even help
