Answer 1

Answer:

2,0

Step-by-step explanation:

Divisibility test of 3=Sum of digits should be

divisible by 3

1)3_6724

Let the digit be x

Sum of digits=3+x+6+7+2+4=22+x

22+×=24 → x=2

or

22+x=27 → x=5

or

22+x=30 → x=8

Smallest answer → 2

2)4765_2

Let the digit be a.

Sum of digits=4+7+6+5+a+2=24+a

24+a=24 → a=0

or

24+a=27 → a=3

or

24+a=30 →a=6

or

24+a=33 →a=9

Smallest answer→0
