Answer

False; $\frac{7}{10}$

Work Step by Step

This is wrong because they added the denominators instead of changing the fractions to have common denominators and then adding the numerators. $\frac{1}{2}$+$\frac{1}{5}$ $\frac{1\times5}{2\times5}$+$\frac{1\times2}{5\times2}$ $\frac{5}{10}$+$\frac{2}{10}$=$\frac{7}{10}$
