What is 872 rounded to the nearest ten
The Correct Answer and Explanation is :
The number 872 rounded to the nearest ten is 870.
Explanation:
When rounding a number to the nearest ten, we look at the digit in the ones place to decide whether to round up or down. In the case of 872, the steps are as follows:
- Identify the tens and ones digits:
- The number 872 has 7 in the tens place and 2 in the ones place.
- Determine whether to round up or down:
- The rule for rounding is simple:
- If the ones digit is 5 or greater, you round up the tens digit by 1.
- If the ones digit is less than 5, you round down, meaning the tens digit remains the same.
- Apply the rule to 872:
- The ones digit is 2, which is less than 5.
- Since 2 is less than 5, we round down. This means the tens digit, 7, stays the same.
- Change the ones digit to 0:
- After rounding, we replace the ones digit with 0 to reflect the nearest ten.
Thus, 872 becomes 870 when rounded to the nearest ten.
Why rounding matters:
Rounding numbers helps simplify calculations, making it easier to estimate results or communicate numbers clearly. For example, if you’re working with large quantities, exact figures may not be necessary, and approximations (like rounding to the nearest ten or hundred) are often more practical.
Rounding can be used in a wide variety of fields, including finance, education, engineering, and everyday situations like shopping or budgeting, where an exact number isn’t always required.
