Question

Write the smallest and greatest digits in the blank so that the number is divisible by 3. a. 406_39​

Answer 1

Answer:

2 is the smallest and 8 is the greatest

Step-by-step explanation:

Since we know,

If the sum of digits is divisible by 3, then the number is divisible by 3.

Since the sum of digits of the given number= 22,which is not divisible by 3.

Therefore, by adding 2 to sum of digits=

22+2=24 which is divisible by 3.

Therefore 2 is the smallest number.

Now, by adding 8 to the sum of digits=

22+8=30 which is divisible by 3.

Therefore, 2 and 8 are the smallest and the greatest number respectively,which will be written in the blank.
