__Objectives:__

At the end of this lesson, students should know what fractional parts are and be able to find fractions of whole numbers or quantities.

**NOTE:**

The fractional part of a whole number or quantity involves finding the number or quantity that makes up that fraction of the whole number or quantity. It involves multiplying fractions and whole numbers.

__Example 1__

1/2 of 10 apples

We know that half of 10 apples is 5 apples as shown below.

When finding fractional parts, we simply divide the whole number by the denominator of the given fraction:

I.e. 1/2 of 10 apples also mean 1/2 x 10 apples

10 ÷ 2 = 5

The next step is to multiply the result by the numerator.

I.e. 5 x 1 = 5

Hence, 1/2 of 10 apples is 5 apples.

__Example 2__

What 3/4 is of 20?

3/4 of 20= 3/4 X 20/1 **This means dividing 20 by 4 and multiply your results by 3.**

20 **÷** 4 = 5 **that is 20****÷****4=5,** **Multiply 5 by 3**

5 X 3 = 15

Hence 3/4 of 20 is 15.

**Example 3**

2/5 of 30 =2/5 X 30/1 **This means dividing 30 by 5 and multiply your result by 2.**

30 ÷ 5 = 6

6 X 2 = 12

Hence 2/5of 30 = 12.
