1. Dividing whole number by a decimal

2. EXAMPLE 1
Find 54 ÷ .12
Before we divide, we need to convert the divisor into a whole number.
In the divisor there are two digits after the decimal point.
So we have to multiply both dividend and divisor by 100

3. EXAMPLE 1
Divide as usual. )
5400 12 48 60
- 60
4 5 0
Ans : 15.6 ÷ .12 = 450

4. EXAMPLE 2
Find 25 ÷ 0.5
Before we divide, we need to convert the divisor into a whole number.
In the divisor there is one digit after the decimal point.
So we have to multiply both dividend and divisor by 10

5. EXAMPLE 2
Divide as usual. )
250 5
5 0
-25
- 0
Ans : 25 ÷ 0.5 = 50

6. Example :Converting divisor into a whole number.
In the divisor there is 1 digit after the decimal point. So we have to multiply both dividend and divisor by 10
6÷1.5
In the divisor there is 2 digits after the decimal point. So we have to multiply both dividend and divisor by 100
5÷.25
In the divisor there is 1 digit after the decimal point. So we have to multiply both dividend and divisor by 10
525 ÷2.5

7. Try these
22 ÷ 0.5
5 ÷ 0.02
27 ÷ 0.6
