## Multiplying Fractions
A fraction is generally used to represent a number which is a ratio of two numbers.
Consider the fraction <span class="fraction"><sup>4</sup><sub>5</sub></span>, here 4 is called the numerator and 5 is called the denominator.
Here are the steps to multiply two fractions
1. Multiply the numerator and denominator of the fractions
2. If possible, simplify the resultant fraction
#### Example 1
<pre> <span class="fraction"><sup>4</sup><sub>5</sub></span> &times; <span class="fraction"><sup>3</sup><sub>5</sub></span> = <span class="fraction"><sup>(4 &times; 3)</sup><sub>(5 &times; 5)</sub></span> = <span class="fraction"><sup>12</sup><sub>25</sub></span> </pre>
#### Example 2
<pre> <span class="fraction"><sup>4</sup><sub>5</sub></span> &times; <span class="fraction"><sup>3</sup><sub>2</sub></span> = <span class="fraction"><sup>(4 &times; 3)</sup><sub>(5 &times; 2)</sub></span> = <span class="fraction"><sup>12</sup><sub>10</sub></span> = <span class="fraction"><sup>6</sup><sub>5</sub></span> (Simplified) </pre>
#### Example 3
Multiplying fractions with whole number.
Please note that a whole number can also be considered as a fraction by considering it's denominator as 1.
<pre> <span class="fraction"><sup>4</sup><sub>5</sub></span> &times; 2 = <span class="fraction"><sup>(4 &times; 2)</sup><sub>(5 &times; 1)</sub></span> = <span class="fraction"><sup>8</sup><sub>5</sub></span> </pre>
