What is rounding?

Rounding is the mathematical process of approximating a number to a specified level of precision or a particular place value. This involves adjusting the number slightly to make it easier to work with or understand, typically by changing the smaller digits to zero or to the next closest larger digit based on a set of rules.

How do you round to the nearest ten?

To round a number to the nearest ten, look at the digit in the ones place. If it's 5 or higher, round up by adding 1 to the digit in the tens place and changing all the digits after the tens place to zero. If it's 4 or lower, keep the digit in the tens place the same and change all the digits after the tens place to zero.

How do you round to the nearest hundred?

To round a number to the nearest hundred, look at the digit in the tens place. If it is 5 or greater, round the hundreds place up by 1. If the tens place digit is less than 5, keep the hundreds place the same. Then, replace all the digits to the right of the hundreds place with zeros. For example, if you have the number 598, the digit in the tens place is 9, so you round up to 600. If you have the number 427, the digit in the tens place is 2, so you keep 400 as it is.

What is the rule for rounding up?

The rule for rounding up is to raise the digit being rounded to the next highest value when the digit to its right is 5 or greater.

What is the rule for rounding down?

The rule for rounding down is to keep the digit to the right of the rounding position the same if it is less than five. This means that any decimal less than 0.5 should be rounded down to the nearest whole number or decimal place.

What is a benchmark number?

A benchmark number is a standard value used for comparison or evaluation in various contexts, such as financial performance, project progress, or data analysis. Benchmark numbers serve as reference points to measure and assess the performance, efficiency, or quality of a process, product, or service against established standards or industry norms.

How do you use a benchmark number to round?

To use a benchmark number to round, you first need to determine which place value you are rounding to (such as tens, hundreds, etc.). Then, identify the benchmark number closest to the original number in that place value. If the original number is closer to the benchmark number or equal to it, you round down. If the original number is greater than the benchmark number, you round up. This helps make rounding easier and faster by using familiar numbers as reference points to estimate the rounded value of a number.

How do you round a two-digit number to the nearest ten?

To round a two-digit number to the nearest ten, you look at the digit in the units place. If it is 5 or larger, you round up by increasing the digit in the tens place by one and changing the digit in the units place to zero. If the units digit is 4 or smaller, you simply change the units digit to zero.

How do you round a three-digit number to the nearest hundred?

To round a three-digit number to the nearest hundred, look at the tens and units digits. If the tens digit is 5 or greater, you round the hundreds digit up by one. If the tens digit is less than 5, you keep the hundreds digit as it is. Finally, replace the tens and units digits with zeros. For example, if you have the number 643, the tens digit is 4 (less than 5), so the hundreds digit remains 6. Thus, you would round 643 to 600.

How do you round a four-digit number to the nearest thousand?

To round a four-digit number to the nearest thousand, look at the hundreds place value. If the hundreds place value is 500 or greater, increase the thousand place value by 1 and replace the hundreds, tens, and ones with zeros. If the hundreds place value is less than 500, replace the hundreds, tens, and ones with zeros.
