Question

What should be subtracted from $\frac{-1}{8}$ to get $\frac{3}{4}$ ?

• A. True
• B. False
• C. $\frac{-1}{8}$
• D. $\frac{1}{8}$

Answer 1

The correct option is A

True

Let the required number be $x$

$\therefore$ $\frac{-1}{8}$ - $x$ = $\frac{3}{4}$
$\Rightarrow$ $\frac{3}{4}$ + $\frac{1}{8}$ = - $x$
$\Rightarrow$ $\frac{3\times 2}{4\times 2}$ + $\frac{1}{8}$ = - $x$

( LCM of 4 and 8 is 8 )

$\Rightarrow$ $\frac{6}{8}$ + $\frac{1}{8}$ = - $x$
$\Rightarrow$ $\frac{6+1}{8}$ = - $x$

$\Rightarrow$ $x$ = $\frac{-7}{8}$
