Question

in each of the following number, replaced* by a digit to make the number divisible by 3 (i) 156*9​

Answer 1

Answer:

3

Step-by-step explanation:

we know the rule for divisibility for 3

i.e. if sum of digits of number is divisible by 3 then this number is also divisible by 3

here sum of 1+5+6+9=21

next to 21 we know 24 is divisible by 3

so we replace 3 instead of *

now sum is 24 which is divisible by 3
