A two-digit number is divisible by 4 if, when you divide it by 4, the remainder is zero. This is the basic principle for any division.
Understanding Divisibility by 4
To determine if a two-digit number is divisible by 4, you can perform the division and check the remainder. The reference provided states that a number is divisible by 4 "when we divide and see that the remainder is zero."
Here's a breakdown:
| Action | Explanation |
|---|---|
| Divide | Divide the two-digit number by 4. |
| Check Remainder | If the remainder is 0, then the number is divisible by 4. |
Examples
- Example 1: Is 24 divisible by 4?
- 24 divided by 4 equals 6 with a remainder of 0.
- Therefore, 24 is divisible by 4.
- Example 2: Is 25 divisible by 4?
- 25 divided by 4 equals 6 with a remainder of 1.
- Therefore, 25 is not divisible by 4.
Practical Application
You can use long division or a calculator to perform the division. If the result is a whole number (without any decimal or fractional part), it means the remainder is zero, and the original number is divisible by 4.
