Question

Find the number divisible by 3 from the number 12,23,36,48,52,57,4735.​

Answer 1

Answer:

12,36,48,57

Step-by-step explanation:

To check the number is divisible by 3,

we have to check the divisibility rule of 3.

i.e divide the number by 3 if it is completely divisible by 3, and leaving a remainder zero, then it is divisible by 3, if the remainder is other than zero, then it is not divisible by zero.

Now, check the number

12/3=4

36/3=12

48/3=16

57/3=19

These numbers are multiples of 3 and leave zero remainders. Hence these numbers 12,36,48,57 are divisible by 3.

The numbers 23,52,4735 are not divisible by 3, as they have a remainder other than zero when divided by 3.

Answer 2

Answer:

Numbers Divisible by 3 are : 12,36,48,57

Step-by-step explanation:

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

Here sum of digits of 12 = 1+2 =3 (divisible by 3)

         sum of digits of 23 = 2+3 =5 (not divisible by 3)

        sum of digits of 36 = 3+6 =9 (divisible by 3)

         sum of digits of 48 = 4+8 = 12(divisible by 3)

         sum of digits of 52 = 5+2 = 7 (not divisible by 3)

        sum of digits of 57 = 5+7 = 10 (not divisible by 3)

         sum of digits of 4735 = 4+7+3+5 = 19 ( not divisible by 3)

Hence Numbers that are divisible by 3 : 12,36,48,57
