Rule
A number is divisible by 2 if it has any of the digits 0, 2, 4, 6, or 8 in its ones place.
CISCE: Class 6
Step-by-Step Explanation
CISCE: Class 6
Examples
| Number | Last Digit | Divisible by 2? | Why |
|---|---|---|---|
| 42 | 2 | Yes | 2 is even |
| 75 | 5 | No | 5 is odd |
| 100 | 0 | Yes | 0 is even |
| 119 | 9 | No | 9 is odd |
| 68 | 8 | Yes | 8 is even |
CISCE: Class 6
Real-Life Application
Imagine you have 8 chocolates to share with your friend.
-
If you share equally, each gets 4 chocolates (8 ÷ 2 = 4).
-
Nothing is left over, so 8 is divisible by 2.
Now suppose you have 9 chocolates:
-
Each gets 4, but 1 is left out—so 9 is not divisible by 2.
CISCE: Class 6
Key Points Summary
-
Check the last digit.
-
If the last digit is 0, 2, 4, 6, or 8 → divisible by 2 (even number).
-
If the last digit is 1, 3, 5, 7, or 9 → NOT divisible by 2 (odd number).
