Question

Subtract the sum of $\frac{-5}{7}$ and $\frac{-8}{3}$ from the sum of $\frac{5}{2}$ and $\frac{-11}{12}$.

• A. $4\frac{27}{28}$
• B. $3\frac{27}{28}$
• C. $2\frac{27}{28}$
• D. $\frac{27}{28}$

Answer 1

The correct option is A $4\frac{27}{28}$

$\frac{-5}{7}+\frac{-8}{3}=\frac{-71}{21}$

$\frac{5}{2}+\frac{-11}{12}=\frac{19}{12}$

So, $\frac{19}{12}-\frac{-71}{21}=\frac{417}{84}=\frac{139}{28}=4\frac{27}{28}$
