Question

check the divisibility conditions of 2 ,3 from the following number 87 2645​

Answer 1

Answer:

The number is not divisible by 2 because it is not ending with a even number.

The number is not divisible by 3 because it s sum is not 3, 6 or 9

Step-by-step explanation:

Answer 2

Step-by-step explanation:

A number is only divisible by 2 if the unit digit of the number is even.

A number is only divisible by 3 if the sum of all digits of the number is a multiple of 3.

here 87 and 2645 are not divisible by 2 as both of them don't have an even digit at units place.

now, 8+7 = 15, which is a multiple of 3. Therefore 87 is divisible by 3

87/3 = 29

And, 2+6+4+5 = 17 is not a multiple of three, hence 2645 is not divisible by 3
