There are 200 integers between 1 and 1000 that are divisible by 5, and 800 that are not.
Understanding Divisibility by 5
To find the number of integers divisible by 5 between 1 and 1000, we perform a simple calculation:
- Divide the upper limit by 5: 1000 / 5 = 200
This gives us the number of multiples of 5 within the range. Therefore, there are 200 integers divisible by 5.
Integers Not Divisible by 5
Since there are 1000 integers between 1 and 1000 (inclusive), and 200 of them are divisible by 5, the remaining integers are not divisible by 5. This is calculated as:
- Subtract the divisible numbers from the total: 1000 - 200 = 800
Thus, there are 800 integers between 1 and 1000 that are not divisible by 5.
Summary
- Divisible by 5: 200
- Not divisible by 5: 800
This information is supported by various online resources and mathematical principles. The referenced snippets confirm this straightforward calculation.
