Question

write the divisibility rules of number 2 3 5 6 9 and 11 explain with two examples​

Answer 1

Step-by-step explanation:

• 2 = A number is divisible by 2 if it's one's digit is 0,2,4,6 or 8.

Example : (i) 564 is divisible by 2

(ii) 135 is not divisible by 2

• 3 = A number is divisible by 3, if the sum of its digits is divisible by 3.

Example : (i) 12 = 1+2 = 3 which is divisible by 3

(ii) 15 = 1+5 = 6 which is divisible by 3

• 5 = A number is divisible by 5 if its one's digit is either 0 or 5.

Example : (i) 55 is divisible by 5

(ii) 60 is divisible by 5

• 6 = A number is divisible by 6 if it is divisible by both 2 and 3

Example : (i) 24 is divisible by 6

(ii) 36 is divisible by 6

• 9 = A number is divisible by 9 if the sum of its digits is divisible by 9

Example : (i) 27 = 2+7 = 9 is divisible by 9

(ii) 54 = 5+4 = 9 is divisible by 9

• 11 = A number is divisible by 11 if the difference of the sums of the digits at the odd places (from the right) and at the even places (from the right) is divisible by 11

Example : (i) 121

Sum of digits at odd places (from the right) = 1+2 = 2

Sum of digits at even places (from the right) = 2

Difference = 2-2 = 0 [ Yes it is divisible by 11 ]

(ii) 616

Sum of digits at odd places (from the right) = 6+6 = 12

Sum of digits at even places (from the right) = 1

Difference = 12-1 = 11 [ Yes it is divisible by 11 ]
