Dividing Numbers

In dividing numbers we will learn division by 20, 30, 40, …………………, 90, etc.

For examples:

1. Divide 80 ÷ 20

Solution:

80 ÷ 20 = 80 ÷ (2 x 10) = 80 ÷ 2 ÷ 10

We divide 80 by 2 and then the obtained quotient is divided by 10.

So, final quotient = 4

Thus, the quotient = 4

2. Divide 60 ÷ 30

Solution: 

60 ÷ 30 = 60 ÷ (3 x 10) = 60 ÷ 3 ÷ 10

We divide 60 by 3 and then the obtained quotient is divided by 10.

So, final quotient = 2

Thus, the quotient = 2

3. Divide 240 by 40

Solution:

240 ÷ 40 = 240 ÷ (4 x 10) = 240 ÷ 4 ÷ 10

We divide 240 by 4 and then the obtained quotient is divided by 10.

So, final quotient = 6,

Thus, the quotient = 6

4. 320 ÷ 80

Solution:

320 ÷ (8 x 10)

So, quotient = 4

(Note: This method is applicable only when dividend is completely divisible by divisor.)
