Patterns in numbers

Patterns in numbers

Identify the patterns in multiplication and division (multiples of 9).

The multiples of 6 is coloured in orange for you.

Similarly, Colour the multiples of 5 in blue, Multiples of 9 in Red, Multiples of 10 in Green, Multiples of 11 in Pink.

Let us Know

Multiply any number by 9, the sum of all the digits of the product is 9.

Example : 1

 84 x 9 = 756

7 + 5 + 6 = 18

 = 1 + 8

 = 9

Example : 2

 43 x 9 = 387

3 + 8 + 7 = 18

 = 1 + 8

 = 9

Example : 3

 123 x 9 = 1107

1 + 1 + 0 + 7 = 9

Activity

Make patterns based on the multiples of 9.

Remember: If the sum of all digits of a number is 9 or divisible by 9, then the number is called multiple of 9.
