Question

8*711 by the smallest number to make it divisible by 3

Answer 1

Step-by-step explanation:

If a no is divisible by 3 then the sum of its digits must be divisible by 3

we have

8+*+7+1+1

=17+*

therefore the smallest no to be added is

1

because

17+1=18

1+8=9

and 9 is clearly divisible by 3
