Question

Identify the numbers which are divisible by 3
52,97,99,108,465​

Answer 1

Answer:

answer is 99 because 3×3=9

Answer 2

Answer:

99,108 and 465

Solution:

Divisibility rule of 3

Divisibility rule for 3 states that a number is completely divisible by 3 if the sum of its digits is divisible by 3.

1)52

To find out if 52 is divisible by 3, we will add up the digits that make

52 as follows: 5 + 2 = 7.7 is not the multiple of 3.

Hence 52 is not divisible by 3.

2)97

To check whether 97 is divisible by 3 or not,take the sum of the digits

ie,9+7=16

16 is not the multiple of 3.

Hence 97 is not divisible by 3.

3)99

To find out if 99 is divisible by 3, we will add up the digits that make 99 as follows: 9 + 9 = 18

We know that if the sum of the numbers that make up 99 is divisible by 3, then 99 is divisible by 3.

Since the sum of the digits in 99 is divisible by 3,

99 is also divisible by 3.

4)108

Any number will be divisible by 3 only if the sum of all the digits in that number will be divisible by 3.

Sum of digits of number 108 = 1 + 0 +8 = 9 which is divisible by 3.

Hence we conclude number 108 is divisible by 3.

5)465

To check whether 465 is divisible by 3 or not, take the sum of the digits

ie,4+6+5=15

15 is divisible by 3

So 465 is divisible by 3.

Hence,99,108 and 465 are divisible by 3.
