**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.

**Do you know**

1 2 3 4 5 6 7 9 x 9
= 1 1 1 1 1 1 1 1 1

1 2 3 4 5 6 7 9 x
18 = 2 2 2 2 2 2 2 2 2

1 2 3 4 5 6 7 9 x
27 = 3 3 3 3 3 3 3 3 3

1 2 3 4 5 6 7 9 x
36 = 4 4 4 4 4 4 4 4 4

1 2 3 4 5 6 7 9 x
45 = 5 5 5 5 5 5 5 5 5
