Question

Which rational number should be subtracted from $\frac{-7}{9}$ to get $\frac{5}{6}$ ?

• A. $\frac{-29}{18}$
• B. $\frac{-26}{18}$
• C. $\frac{-19}{18}$
• D. $\frac{-13}{18}$

Answer 1

The correct option is A

$\frac{-29}{18}$

Let the number be $x$.

$\frac{-7}{9}-x$ = $\frac{5}{6}$

$\Rightarrow x$ = $\frac{-7}{9}-\frac{5}{6}$ = $\frac{-14-15}{18}$ = $\frac{-29}{18}$
