There are 534 car parking spaces but 478 spaces are occupied,round to the nearest 10
The Correct Answer and Explanation is:
To round the number of occupied car parking spaces (478) to the nearest ten, we focus on the last digit, which is in the ones place.
Here’s the step-by-step process for rounding 478 to the nearest ten:
- Identify the ones digit: The number 478 has a ones digit of 8.
- Apply rounding rules:
- If the ones digit is 5 or greater, round the number up to the nearest ten.
- If the ones digit is less than 5, round the number down to the nearest ten.
- Rounding the number: Since the ones digit is 8 (which is greater than 5), we round the number up. The nearest ten to 478 is 480.
Thus, 478 rounded to the nearest ten is 480.
Why Round to the Nearest Ten?
Rounding numbers to the nearest ten simplifies calculations, especially when you need to estimate or approximate values quickly. This is useful in various scenarios like budgeting, estimating the number of items, or determining space utilization.
For example, in the case of parking spaces, rounding the number of occupied spaces to the nearest ten helps to quickly assess the overall utilization of the parking area without focusing on the exact number. Instead of saying “478 spaces are occupied,” you could say “480 spaces are occupied,” which is easier to work with in everyday discussions or when providing a general overview.
In summary, rounding 478 to the nearest ten gives us 480 because the ones digit is 8, which is greater than 5. This is the standard rounding rule that helps to make numbers more manageable for estimation purposes.
