Question

If $6:8$ and $3:x$ are equivalent ratios, the value of $x$ will be:

• A. 4

Answer 1

The correct option is A 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.

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