Question

the smallest missing digit in the number 4678*9 so that the number is divisible by 9 is --------​

Answer 1

Answer: '2' will be the smallest missing digit in 4678*9 so this number this divisible by 9.

Step-by-step explanation:

divisiblity rule of 9 is that sum of digits is divisible by 3 & 9

so,

let the missing digit 'x'

4+6+7+8+x+9=divisible of 3 & 9

34+x=divisible of 3 & 9

so if we put x = 2 then the number will became 36 so it is divisible by 3 & 9

so our ANSWER is '2'

Answer 2

Answer:

2

Step-by-step explanation:

Let the missing number be y

Divisibility rule of 9: Addition of all numbers equal to 9

Therefore, 4 + 6 + 7 + 8 + y + 9 =9

                  34 + y = 9

Now to make the number equal to 9, we have to add the digits of 34

3+4=7

To get the value of y, we will have to subtract 7 from 9

y=9-7

 =2
