Question

Larry received 1/3 pound of candy from his grandmother and 2/5 pound of candy from his best friend. Larry’s sister ate 1/2 pound of candy. How many pounds of candy does Larry have?

Answer 1

7/30 pounds of candy

Explanation:

1/3 + 2/5 = 11/15

11/15 - 1/2= 7/30 pound of candy

Answer 2

`\bf \stackrel{\textit{granny's}}{\cfrac{1}{3}}+\stackrel{\textit{friend's}}{\cfrac{2}{5}}-\stackrel{\textit{sister}}{\cfrac{1}{2}}\implies \stackrel{\textit{using an LCD of 30}}{\cfrac{(10)3+(6)2-(15)1}{30}}\implies \cfrac{30+12-15}{30} \\\\\\ \cfrac{27}{30}\implies \cfrac{9}{10}`
