Question

You received 1⁄3 pound of candy from your grandmother, 1⁄2 pound of candy from your sister, but your best friend ate 1⁄5 pound of candy. How much candy do you have left?

Answer 1

you set the same denominator which would become

2/6 and 3/6

5/6 is how much chocolate you get

Now you set the same denominator again

50/60 and 12/60

subtraction would cause

38/60 is amount of candy left
simplify to 19/30

Answer 2

give them the same denominator.
19/30 is what you have left
