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


Sagot :

Given:

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

To find:

The value of x.

Solution:

We have,

[tex]2:x\equiv 12:18[/tex]

It means,

[tex]\dfrac{2}{x}=\dfrac{12}{18}[/tex]

[tex]2\times 18=12\times x[/tex]

[tex]36=12x[/tex]

Divide both sides by 12.

[tex]\dfrac{36}{12}=\dfrac{12x}{12}[/tex]

[tex]3=x[/tex]

Therefore, the value of x is 3.
