Answer:
m = 1
Explanation:
A number is divisible by 3 if the sum of the digits is a multiple of 3
the given number is 2m234 and we are asked to find the smallest m
Adding up known digits gives 2 + 2 + 3 + 4 = 11
The next multiple of 3 is 12
So 11 + m = 12
m = 1
The other possibilities are
m = 4, m = 7
