Larry

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

Correct answer:

x =  0.2333 lb

Step-by-step explanation:

$$\begin{gathered} a=\frac{1}{3}+\frac{2}{5}=\frac{5}{15}+\frac{6}{15}=\frac{5+6}{15}=\frac{11}{15}\doteq 0.7333\text{lb} \\ x=a-\frac{1}{2}=\frac{11}{15}-\frac{1}{2}=\frac{22}{30}-\frac{15}{30}=\frac{22-15}{30}=\frac{7}{30}=\frac{7}{30}\text{lb}=0.2333\text{lb} \end{gathered}$$
