Shortcuts in Division

There are so many types of divisions are there. Lets have a look.


Division by parts --> Imagine you have Rs.874 . You have to give that to your two children.

874/2    [We can write this 874 as 800+74 (for our convenience)

= 800/2 + 74/2

= 400 + 37

= 437 


Division using the factors of the divisor: "this is also called as Double Division"

70/14

= (70/7)/2    (Because 7 and 2 are the factors of 14)

= 10/2

= 5


Division using Fractions:

132/2

= (100/2 + 32/2) ( here we've broken the given fraction into two separate fractions)

= (50 + 16)

= 66


Division by 5 :

Note: if you have to divide any number with 5, then divide it by 100 and then just multiply by 20

1400/5

= (1400/100) x 20

= 14 x 20

= 280

Division by 10 (Its very simple, just move the decimal point one place to the left)

0.5/10

= 0.05 


Division by 50 ( Just divide with 100 then multiply by 2)

2100/50

= (2100/100) x 2

= 21 x 2

= 42


700/50

= (700/100) x 2

= 7 x 2

= 14

Division by 100 (just move the decimal point two places to the left)

25/100 

= 0.25


Division by 500 (just divide with 100 and then multiply with 0.2)

17/500 

= (17/100) x 0.2 

= 0.17 x 0.2

= 0.034


Division by 25 (just divide by 100 and then multiply by 4 )

500/25

= (500/100) x 4

= 5 x 4

= 20


750/25

= (750/100) x 4

= 7.5 x 2 x 2

= 30
