Division using the factors of the divisor
This method is also called Double Division.
Here you can directly divide 75 by 15 and the answer would be 5. But, to understand this method, we are not doing like that.
Now, factories divisor.
So we can write 15 as 5 × 3.
Now we can divide 75 by 3 which gives us 25.
Now we can divide 25 by 5 and that gives 5 as answer.
So the answer is 5.
Division By Parts
Write 75 as 45 + 30
So we can write
=
So the answer is 5.
Division by 10
Just move the decimal point one place to the left side.
So the answer is 1.256
Division by 5
Divide the dividend by 100 and multiply by 20.
So the answer is 40
