Question

check whether 321 and 890 are divisible by 3 or not​

Answer 1

Answer:

Is 321 divisible by 3? In other words, if you divide 321 by 3, will you get a whole number with no remainder?

Of course, you could use a calculator to find out if 321 is divisible by 3, but what fun would that be?

To find out if 321 is divisible by 3, we will add up the digits that make 321 as follows: 3 + 2 + 1 = 6

We know that if the sum of the numbers that make up 321 is divisible by 3, then 321 is divisible by 3.

Since the sum of the digits in 321 is divisible by 3, 321 is also divisible by 3. Thus, the answer to the question "Is 321 divisible by 3?" is as follows:

Yes

Is 890 divisible by 3? In other words, if you divide 890 by 3, will you get a whole number with no remainder?

Of course, you could use a calculator to find out if 890 is divisible by 3, but what fun would that be?

To find out if 890 is divisible by 3, we will add up the digits that make 890 as follows: 8 + 9 + 0 = 17

We know that if the sum of the numbers that make up 890 is divisible by 3, then 890 is divisible by 3.

Since the sum of the digits in 890 is not divisible by 3, 890 is also NOT divisible by 3. Thus, the answer to the question "Is 890 divisible by 3?" is as follows:

No

Answer 2

Answer:

Divisibility rule of 3 - It's sum should be divisible by 3

So, 321 ----- 3+2+1 = 6

6 is divisible by 3

So, 321 is divisible by 3.

Then, 890 ------ 8+9+0 = 17

17 is not divisible by 3

Hence, 890 is not divisible by 3.
