Final answer:
To round numbers to the specified place values, look at the digit right of the place being rounded. If it's 5 or greater, round up; if it's less than 5, round down. For example, 13786 rounds to 14000 for thousands and 9867 rounds to 9870 for tens.
Step-by-step explanation:
To round numbers to the nearest tens, hundreds, thousands, ten thousands, hundred thousands, we look at the digit in the place value being rounded to and follow these rules:
- If the digit in the next smaller place value is less than 5, we round down. For example, 13786 rounds to 13780 when rounded to the nearest ten.
- If the digit in the next smaller place value is 5 or greater, we round up. For example, 13786 rounds to 13790 when rounded to the nearest ten.
- If the digit in the next smaller place value is 5 and followed by nonzero digits, we round up. For example, 13786 rounds to 13790 when rounded to the nearest ten.
Using these rules, here are the rounded values:
- 13786 rounds to 13790 (to the nearest ten)
- 718751 rounds to 718800 (to the nearest hundred)
- 3856768 rounds to 3857000 (to the nearest thousand)
- 5896 rounds to 5900 (to the nearest hundred)
- 89716 rounds to 89720 (to the nearest ten thousand)
- 187619 rounds to 187600 (to the nearest hundred thousand)
- 4286579 rounds to 4287000 (to the nearest thousand)
- 9867 rounds to 9870 (to the nearest ten)
- 90846 rounds to 90850 (to the nearest ten)
- 896 rounds to 900 (to the nearest hundred)
- 1234567 rounds to 1235000 (to the nearest ten thousand)
- 8765432 rounds to 8765000 (to the nearest ten thousand)
