Answer 1

Answer:

45 is divisible by 3 because 4+5=9 is divisible by 3. Now, the number would be divisible by 3 if the sum of all the digits is divisible by 3. Thus 2 is the smallest digit. Thus 0 is the smallest number.

As 24 is already divisible by 3, the smallest number that can be placed here is 0. If we put 9, then the sum of the digits will be 33 and as 33 is divisible by 3, the number will also be divisible by 3. Therefore, the largest number is 9.

Answer 2

Answer

Divisibility rule of 3=> If sum of number is divisible by 3 then whole number is divisible by 3

so

a) 13_378

=> 1+3+3+7+8 = 22

Smallest number in box is 2

Greatest number in box 8

b) _6724

=> 6+7+2+4 =19

Smallest number in box is 2

Greatest number in box is 8
