Question

The value of $x$ such that $-\frac{3}{8}$ and $\frac{x}{-24}$ are equivalent rational numbers is:

• A. $64$
• B. $-64$
• C. $-9$
• D. $9$

Answer 1

Answer: (D)

$9$

$-\frac{3}{8}$ and $\frac{x}{-24}$ are equivalent rational numbers,

$\Rightarrow$ $-\frac{3}{8}=\frac{x}{-24}$

By cross multiplication,

$\frac{-3\times -24}{8}=x$

$\therefore x=9$
