Multiplying fractions by whole numbers

Any whole number can be multiplied by a fraction. All you have to do is multiply the number by the numerator of the fraction.

For example, multiply the number 5 by a fraction . To solve this example, multiply the number 5 by the numerator of the fraction

The answer is an improper fraction. Let's separate the whole part of the fraction:

If there are five whole pizzas and we take half of that number, we have two whole pizzas and half a pizza:

Example 2. Find the value of the expression

Multiply the number 3 by the numerator of the fraction

The answer is an improper fraction , but we extracted the whole part of it and got 2.

Also, you could have shortened the fraction. The result would have been the same. It would look like this:

If there are three whole pizzas and we take two thirds of that amount, we have two whole pizzas:

Example 3. Find the value of the expression

This example is solved in the same way as the previous ones. The whole and the numerator of the fraction must be multiplied:

Example 4. Find the value of the expression

Multiply the number 3 by the numerator of the fraction
