- 7.25
- 5.33
- 155.51
- 42.90
- 3.65
- 1.23
Explanation:
Rounding numbers to the nearest hundredths means keeping two decimal places and adjusting the second decimal based on the digit that follows it (the thousandths place). The rule is simple:
- If the third decimal digit (thousandths place) is 5 or higher, round up the second decimal digit.
- If it’s 4 or lower, keep the second decimal digit as is.
Let’s apply this rule to each number:
- 13.7556 → The third digit (5) is 5 or more, so round 13.755 to 13.76.
- 38.614 → The third digit (4) is less than 5, so round to 38.61.
- 41.009 → The third digit (9) is 5 or more, so round 41.009 to 41.01.
- 8.6245 → The third digit (4) is less than 5, so round to 8.62.
- 7.2532 → The third digit (3) is less than 5, so round to 7.25.
- 5.325 → The third digit (5) is 5 or more, so round to 5.33.
- 155.513 → The third digit (3) is less than 5, so round to 155.51.
- 42.895 → The third digit (5) is 5 or more, so round to 42.90.
- 3.654 → The third digit (4) is less than 5, so round to 3.65.
- 1.23 → Already at hundredths place; nothing to round, so it remains 1.23.
Rounding is essential in real-life applications like finance, science, and engineering, where precision is balanced with simplicity. Proper rounding ensures consistent and easily interpretable results without unnecessary detail.
