__Objectives:__

At the end of this lesson, students should be able to multiply decimals by whole numbers.

Multiplying means continues addition. It implies adding a particular number to itself a number of times. The same rule applies when multiplying decimals by whole numbers.

Consider the number line below.

**The number line shows four (4) jumps in steps of 0.3 each time. This ends on 1.2. It implies that 0.3 + 0.3 + 0.3 + 0.3 = 1.2**

Using multiplication, we can say that:

0.3 x 4 = 1.2

__Workout:__

0.3

X 4

1.2

Here it is evident that multiplication of decimals follows the normal method of multiplication except that **the answer bears the same number of decimal places as the decimals being multiplied.**

__Example 1__

a. 4.8 x 3 b. 2.65 x 6 c. 1.293 x 8 d. 13.4 x

**Solution**

__Example 2__

**Complete the multiplications below.**

a. 0.64 x 12 b. 2.389 x 23
