The document discusses divisibility rules for numbers 2 through 10. It provides examples for each rule and interactive problems for the reader to determine which number is not divisible by the given number. The rules are: a number is divisible by 2 if the last digit is even; divisible by 3 if the sum of the digits is 3, 6, or 9; divisible by 5 if the last digit is a 5 or 0; divisible by 9 if the sum of the digits is 9; and divisible by 10 if the last digit is 0.

1. Divisiblity

2. “Divisible by” means:
If you divide one number by
another, the result is a
whole number WITHOUT
a remainder.
Examples:
12 ÷ 6 = 2 No remainder
15 ÷ 5 = 3 No
remainder

3. Divisibility by 2
A number can be
divisible by 2 if
the last digit is even
(0, 2, 4, 6, 8)
Examples:
6798512=6+7+9+8+5+1
+2=38[which is
divisible by 2]

4. Now You Try:
Which number IS NOT
divisible by 2?
572
1464
249

5. WONDERFUL….!!!

6. Divisibility by 3
a number is divisible by 3 if
the sum of the digits is 3, 6
or 9
Example:123456
1+2+3+4+5+6=21
2+1=3[which is divisible by
3]

7. Now You Try:
Which number IS NOT
divisible by 3?
572
1464
279

8. Way To Go!!

9. Divisibility by 5
A number is divisible by 5
if the last digit is a 5 or a 0
Example:749230=7+4+9+2
+3+0=25[which is divisible
by 5]

10. Now You Try:
Which number IS NOT
divisible by 5?
9820
779
560

11. Good..!!

12. Divisibility by 9
A number is divisible by 9
if
the sum of all the digits will
add to 9
Example:50832=5+0+8+3+
2=18
1+8=9[which is divisible by
9]

13. NowYouTry:
Find the number that
IS NOT divisible
by 9.
9873
636
5541

14. Congratulations!

15. Divisibility by 10
A number is divisible by
10 if
the last digit is a 0
Example:508322=5+0+8
+3+2+2=20 [which is
divisible by 10]

16. NOW YOU TRY:
Find the number that
IS NOT divisible
by ten.
