Answer explanation
What is Rounding?
Rounding is a way to make numbers easier to work with by changing them to the nearest ten or hundred.
Rounding to the Nearest Ten:
Look at the ones place (the last digit).
If the ones digit is 5 or higher, round up. This means you add 1 to the tens place.
If the ones digit is 4 or lower, round down. Keep the tens place the same.
Example:
For 47: The ones digit is 7 (round up to 50).
For 42: The ones digit is 2 (round down to 40).
Rounding to the Nearest Hundred:
Look at the tens place (the second digit from the right).
If the tens digit is 5 or higher, round up to the next hundred.
If the tens digit is 4 or lower, round down.
Example:
For 265: Round up to 300.
For 234: Round down to 200.
