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 = 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.

dividend is completely divisible by diviso








So, final quotient = 6,

Thus, the quotient = 6


4. 320 ÷ 80
