Question

Find the sum: $\frac{3}{10}+\frac{4}{15}$

• A. $\frac{29}{30}$
• B. $\frac{15}{30}$
• C. $\frac{19}{30}$
• D. $\frac{17}{30}$

Answer 1

The correct option is D

$\frac{17}{30}$

LCM of 10 and 15 is 30.

$\frac{3}{10}+\frac{4}{15}$ $=\frac{3\times 3}{10\times 3}+\frac{4\times 2}{15\times 2}=\frac{9}{30}+\frac{8}{30}=\frac{9+8}{30}=\frac{17}{30}$
