5 ⇒ The units place should be either 5 or 0.

10 ⇒ The units place should have 0.

Additional Information ❤

Mention the divisibility Rule for the rest of the numbers.

3 ⇒ The sum of all the digits should be a multiple of 3.

4 ⇒ The last two digits should be divisible by 4.

6 ⇒ The number should be divisible by 2 and 3 to be divisible by 6.

7 ⇒ To see if a number is divisible by 7 we need to double the last digit and subtract the result from the rest of the number.

8 ⇒ The last three digits should be divisible by 8.

9 ⇒ The sum of all the digits should be a multiple of 9.

11 ⇒ To see if a number is divisible by 11 we subtract the last digit from the number from the remaining digits.

12 ⇒ The number should be divisible by 3 and 4 to be divisible by 12.

What does divisible by mean?

When we divide a number by another and get a result as whole number it is known to be divisible by the other number.

Why do we have divisibility rules?

We have these rules because they let us know if a number is divisible by another number without calculating. It just makes our work easier.
