one of the number choices ispssible that the numbermight be dirisible hy more than information in a report, in this onters . Once you determine which divisibility rules apply to the given number, include the following Explain (in a few sentences) the topic of divisibility, including any correct terms that appl Explain each divisibility rule that you determined was true for the given number. These rules should be explained in words a. b. c. After the explanation of the divisibility rule, show ALL work for how the rule applies to t given number d. You should do this for every divisibility rule that you think applies to the given number "You only have to discuss the divisibility rules chosen for the given number Do not give examples ofother numbers and how they are divisible by the divisibility rules

Explanation / Answer

1)Dividing by 2

All even numbers are divisible by 2. E.g., all numbers ending in 0,2,4,6 or 8.

2)Dividing by 3

Add up all the digits in the number.
Find out what the sum is. If the sum is divisible by 3, so is the number.

Here sum of digit is 9 which is divisible by 3 hence 2520 is divisible by 3.

3)Dividing by 4

Are the last two digits in your number divisible by 4?
If so, the number is too!
Here 2520 ends in 20 which is divisible by 4, and so is 2520.

4)Dividing by 5

Numbers ending in a 5 or a 0 are always divisible by 5.

5)Dividing by 6

If the Number is divisible by 2 and 3 it is divisible by 6 also.

6)Dividing by 7 (2 Tests)

Take the last digit in a number.
Double and subtract the last digit in your number from the rest of the digits.
Repeat the process for larger numbers.
Example: 357 (Double the 7 to get 14. Subtract 14 from 35 to get 21 which is divisible by 7 and we can now say that 357 is divisible by 7.

7)Dividing by 9

Almost the same rule and dividing by 3. Add up all the digits in the number.
Find out what the sum is. If the sum is divisible by 9, so is the number.

Here sum is 9 which is divisible by 9 , hence number is divisible by 9.

8) Dividing by 10
