Rounding Numbers
Rounding numbers means making a number simpler but keeping its value close to what it was before rounding. To round off a number, we need to look at the digit at the place value we want to round off and then look at the next digit to the right of it.
Rounding to the nearest tens
To round off a number to the nearest tens, we need to look at the ones digit. If the ones digit is less than 5, we keep the tens digit the same and make the ones digit zero. If the ones digit is 5 or more, we add one to the tens digit and make the ones digit zero.
For example, to round off 482 to the nearest tens, we look at the ones digit which is 2. Since 2 is less than 5, we keep the tens digit 8 and make the ones digit zero. Therefore, 482 rounded to the nearest tens is 480.
Rounding to the nearest hundreds
To round off a number to the nearest hundreds, we need to look at the tens digit. If the tens digit is less than 5, we keep the hundreds digit the same and make the tens and ones digits zero. If the tens digit is 5 or more, we add one to the hundreds digit and make the tens and ones digits zero.
For example, to round off 482 to the nearest hundreds, we look at the tens digit which is 8. Since 8 is greater than 5, we add one to the hundreds digit and make the tens and ones digits zero. Therefore, 482 rounded to the nearest hundreds is 500.
Rounding to the nearest thousands
To round off a number to the nearest thousands, we need to look at the hundreds digit. If the hundreds digit is less than 5, we keep the thousands digit the same and make the hundreds, tens, and ones digits zero. If the hundreds digit is 5 or more, we add one to the thousands digit and make the hundreds, tens, and ones digits zero.
For example, to round off 482 to the nearest thousands, we look at the hundreds digit which is 4. Since 4 is less than 5, we keep the thousands digit 0 and make the hundreds, tens, and ones digits zero. Therefore, 482 rounded to the nearest thousands is 0.
