This exercise is an aid to learning the division tables.
A division operation is deduced from the corresponding multiplication operation. For example :
The multiplication operation |
Corresponds to division operations |
3 x 4 = 12 |
12 : 3 = 4 12 : 4 = 3 |
So, to find the result of a division, you need to look it up in the multiplication table of the divisor. For example :
24 : 4 = ?
In this case, the division is by 4. I search the multiplication table for 4 to find the row with the result 24. I find :
4 x 5 = 20
4 x 6 = 24
4 x 7 = 28
I deduce :
24 : 4 = 6
Remember also the following 3 rules :
- Dividing 0 by any number always gives 0.
- Dividing a number by itself always gives 1.
- Dividing a number by 1 always gives that number.
