MCQ
If $-\frac{3}{4}=\frac{6}{\text{x}},$ then $x =$
✓
$-8$
B
$4$
C
$-4$
D
$8$
✓
Answer
Correct option: A.
$-8$
$-\frac{3}{4}=\frac{6}{\text{x}}$
$\Rightarrow-3\times\text{x}=6\times4$ $\Big(\frac{\text{a}}{\text{b}}=\frac{\text{c}}{\text{d}}\Rightarrow\text{ad}=\text{bc}\Big)$
$\Rightarrow-3\text{x}=24$
$\Rightarrow\frac{-3\text{x}}{-3}=\frac{24}{-3}$ (Dividing both sides by $-3$)
$\Rightarrow\text{x}=-8$
Hence, the correct answer is option $(a)$.
