Answer:

you add the numbers up and if they are a multiple of 3 it can be divided by 3

Step-by-step explanation:

123

1 + 2 + 3 = 6

6 is a multiple

455

4 + 5 + 5 = 14

14 is not a multiple

Step-by-step explanation:

A number, if the sum of its digits is

divisible by 3, is divisible by 3. For example, 375, since the sum of its digits

(3+7+5) is 15, is divisible by 3. And fifteen

is divisible by 3. Divisible by 3 is 1+2=3 and 3.
