Question

anyone can help me for finding algebraic expression for the divisibility rule of 3
it is very urgent guys

Answer 1

Answer:

Step-by-step explanation:

See.. I hope you know the table of 3 upto 10.

I mean,

From

3 X 1 = 3

....

3 X 10 = 30

So,

Example - 1248

Add : 1+2+4+8 = 15

15 comes in the table of 3. So it is divisible by 3.

Now,

Example 27

Add : 2+7 = 9

9 comes in the table of 3. So it is divisible by 3.
