what numbers are divisible by 3?
2007-10-28 07:22:49 · 7 answers · asked by Anonymous in Science & Mathematics ➔ Mathematics
Hi,
Think for a moment about numbers that would be multiplied by 3.
3x1=3
3x2=6
3x3=9
3x4=12
As you can tell, all of these numbers <3,6,9,12,etc.> would be divisible by 3 because they are simply multiples of that one number!
I hope that helps you out! Please let me know if you have any other questions!
Sincerely,
Andrew

The numbers that are divisible by 3 have a distinct property in that their digits when added together, are divisible by 3. This is a divisibility rule for 3 alone. There are similar rule (tricks) for a couple of prime numbers like 2, 5, 7, etc.

the numbers whose digits added together are divisible by 3.
ex : 36 ( 3+6 = 9 divisible by 3)
72 ( 7+2 = 9 divisible by 3)
93 ( 9 + 3 = 12 divisible by 3)

3n, where n = any real rational number
You can also tell if a number is divisible by 3 if the sum of its digits is divisible by 3.

Think of the times tables you had to memorize in second grade.
