MCQ
Mark $(\checkmark)$ against the correct answer in the following:
What should be subtracted from $\frac{-3}{4}$ to get $\frac{5}{6}?$
  • A
    $\frac{19}{12}$
  • $\frac{-19}{12}$
  • C
    $\frac{1}{12}$
  • D
    $\frac{-1}{12}$

Answer

Correct option: B.
$\frac{-19}{12}$
The correct option is $(b).$
Let the number that is to be subtracted be $x.$
$\frac{-3}{4}-\text{x}=\frac{5}{6}$
$\Rightarrow-\text{x}=\frac{5}{6}-\Big(\frac{-3}{4}\Big)$
$\Rightarrow-\text{x}=\frac{5}{6}+\frac{-3}{4}$
$\Rightarrow-\text{x}=\frac{(5\times2)+(3\times3)}{12}$
$\Rightarrow\text{x}=-\frac{19}{12}$
Hence, $\frac{-19}{12}$ should be subtracted from $\frac{-3}{4}$ to get $\frac{5}{6}$
