What is 4,952 rounded to the nearest ten?
The Correct Answer and Explanation is:
Correct Answer: 4,950
Explanation:
To round a number to the nearest ten, we look at the ones digit, which is the last digit of the number.
The number given is 4,952.
- Identify the ones digit:
The ones digit is 2. - Apply the rounding rule:
- If the ones digit is 0–4, you round down.
- If the ones digit is 5–9, you round up.
Since 2 is less than 5, we round down.
- Round the number:
- Keep the tens digit (which is 5) the same.
- Change the ones digit to 0.
So, 4,952 becomes 4,950 when rounded to the nearest ten.
Why Rounding Matters:
Rounding helps simplify numbers, making them easier to estimate, calculate, or compare. For example, when estimating costs or measurements quickly, it’s often more practical to round to the nearest ten, hundred, or thousand.
Additional Examples:
- 4,956 rounded to the nearest ten = 4,960 (since 6 is 5 or more, round up).
- 4,953 = 4,950 (since 3 is less than 5, round down).
- 4,955 = 4,960 (because 5 rounds up).
Summary:
4,952 rounded to the nearest ten is 4,950 because the ones digit is 2, and numbers ending in 0–4 are rounded down to the nearest multiple of ten. This is a basic yet important skill in everyday math.
