Question
The number of whole numbers between $437$ and $487$ is
The correct answer is
49
To find the number of whole numbers between 437 and 487, follow these steps:
- Identify the range of numbers: The problem asks for the whole numbers between 437 and 487. This means we consider numbers greater than 437 and less than 487.
- List the first and last numbers in this range: The first whole number after 437 is 438, and the last whole number before 487 is 486.
- Use the formula for counting numbers between two given numbers: \text{Number of whole numbers} = (\text{last number} - \text{first number}) + 1 In this context, since we are considering numbers between 438 and 486: = (486 - 438) + 1
- Calculate the number: = 486 - 438 = 48 = 48 + 1 = 49
- Conclusion: The number of whole numbers between 437 and 487 is 49.
Thus, the correct answer is 49.
