Which of the following Numbers is divisible by 3

Heres a trick you can use to see if something is divisible by 3.

Step-by-step explanation:

Add up all the numbers and see if thats a multiple of 3. For example, 123 is divisible by 3 because added up, it equals 6 which is divisible by 3.

Can you divide 6, or 9 into it after 5 or 9?

Remember all numbers that end in 1 can only be 21 51 or 81.

All numbers that end in 2 can only be 12 42 72 102

All numbers that end in 4 are 24 54 84

All numbers go up by 15 are 5 = 15, 30, 45, 60, 75, 90

Then you start seeing a pattern until zero 30, 60, 90 is half by 5 this just like 2 to 4 is up to 100.
