Question

Replace# in the number 187# by the smallest possible digit so that the number formed is divisible by 3

Answer 1

Answer:

2

1872 / 3 = 624

Step-by-step explanation:

Divisibility rule for 3 : Sum of digits should be divisible by 3

Therefore:

1+8+7+# = multiple of 3

1+8+7 = 16

Multiples of 3 close to 16: 15,18

Thus, # = 2

1+8+7+2 = 18

18/3 = 6

Answer 2

Answer:

The number in the place of # will be 2 hence the exact number is 11872.

Step-by-step explanation:

The given term 187# , we need to find the smallest possible digit.

We know that the 3 divisible rule. It is sum of all digits is multiple of 3

let # = x

1+8+7+ x

16 +x

16 is not a 3 multiple

So we need to add more to it

17 is also not the multiple of 3

18 is multiple of 3 , Hence we need to add 2 to 16 to get 18

16 +x =18.

16+2=18

we, will see if the number is divisible by 3

1872/3=624

therefore it is divisible by

So the smallest number is 2.

The term will be 1872
