Question

replace the star with the smallest digit to make it divisible by 9 9,08,*18

Answer 1

Answer: hope it works

Step-by-step explanation: call "*" X

6X78905

the rule is to subtract and add the digits in order from left to right and see if the resulting number is divisible by 11

6-X+7-8+9-0+5=19-X

19-X must be divisible by 11

therefore X must be 8 because 19-8=11

6,878,905/11=625,355

Answer 2

Answer:

1

Explanation:

let the number be x

divisibility rule of 9 states that the sum of all the digits of a number should be divisible by 9

so, the sum of 9+ 9 + 0 + 8 + X + 18 = 44+ X

so the smallest number should be X = 1

because then 44+ 1 = 45 which is divisible by 9
