Division Short-Cut Trick

Division by using fractions Division by 5
132/2
= (100/2 + 32/2) ---> break down into two fractions
= (50 + 16)
= 66
1400/5
= (1400/100) x 20---> divide by 100 then multiply by 20
= 14 x 20
= 280
Division by 10 Division by 50
0.5/10
= 0.05 ---> 5% is 50% divided by ten

2100/50---> divide by 100 then multiply by 2
= (2100/100) x 2
= 21 x 2
= 42
Division by 100 Division by 500
25/100---> move the decimal point two places to the left
= 0.25
17/500
= (17/100) x 0.2---> divide by 100 then multiply by 0.2
= 0.17 x 0.2
= 0.034
Division by 25 Division by parts
500/25 ---> divide by 100 then multiply by 4
= (500/100) x 4
= 5 x 4
= 20

Imagine dividing $874 between two persons
874/2
= 800/2 + 74/2
= 400 + 37
= 437
750/25---> divide by 100 then multiply by 4
= (750/100) x 4
= 7.5 x 2 x 2
= 30
Division using the factors of the divisor: "double division"
70/14
= (70/7)/2 ---> 7 and 2 are the factors of 14
= 10/2
= 5
