Question

If $6:8$ and $3:x$ are equivalent ratios, find the value of $x$.

• A. $3$
• B. $4$
• C. $5$
• D. $6$

Answer 1

The correct option is B $4$

Since $6:8$ and $3:x$ are equivalent ratios, we can write $\frac{6}{8}=\frac{3}{x}$.
For finding the value of $x$, we will cross multiply the numbers.

$x=\frac{(3\times 8)}{6}=\frac{24}{6}=4$
