Rounding to the Nearest 100

The video tutorial explains how to round numbers to the nearest 100. It begins with an introduction to rounding and the use of benchmarks and midpoints. The process is demonstrated with examples, showing how to determine the closest hundred by comparing numbers to midpoints. The tutorial concludes with a summary of the steps involved in rounding numbers to the nearest 100.

What is the purpose of rounding a number?

• To decrease the number's value

• To increase the number's value

• To make a number easier to work with

• To make calculations more complex

When rounding to the nearest 100, what is the role of the midpoint?

• It is used to find the exact number

• It is the same as the benchmark

• It is always ignored

• It determines if we round up or down

If a number is exactly at the midpoint between two hundreds, what should you do?

• Round it down

• Round it to the nearest ten

• Round it up

• Leave it as it is

What is the rounded value of 320 to the nearest 100?

• 350

• 400

• 300

• 200

Which step is NOT part of the rounding process to the nearest 100?

• Locate the number on the number line

• Determine the midpoint

• Find the closest tens

• Identify the benchmark numbers
