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,

`(2)/(x)=(12)/(18)`

`2* 18=12* x`

`36=12x`

Divide both sides by 12.

`(36)/(12)=(12x)/(12)`

`3=x`

Therefore, the value of x is 3.
