Question

Identify the value of x that makes each pair of ratios equivalent. 2:x and 12:18

Answer 1

Given:

Two ratios 2:x and 12:18 are equivalent.

To find:

The value of x.

Solution:

We have,

$2:x\equiv 12:18$

It means,

$\dfrac{2}{x}=\dfrac{12}{18}$

$2\times 18=12\times x$

$36=12x$

Divide both sides by 12.

$\dfrac{36}{12}=\dfrac{12x}{12}$

$3=x$

Therefore, the value of x is 3.
