Ratio and Proportion

• Value of $\boldsymbol{x}$ can be found by using concept of ratio and proportion.
• A ratio expresses the amount of times one number contains the other.
• A proportion is a mathematical expression in which two ratios are specified to be equal.
• The ratio is used to compare the sizes of two objects that have the same unit of measurement. The proportion is a mathematical expression that expresses the relationship between two ratios.

Consider the following equation:

$72:64=x:16$

       $\frac{72}{64}=\frac{x}{16}$

     $64x=72\times 16$

         $x=\frac{72\times 16}{64}$

            $=18$

So, value of $x$ is $\boldsymbol{18}$.
