To round off numbers to the nearest 100, we need to look at the tens digit (the second digit from the right). If the tens digit is 5 or greater, we round up; if it is less than 5, we round down. Let's analyze each number step by step: ### a. 345882 - **Tens digit**: 8 (from 345882) - Since 8 is greater than 5, we round up. - **Rounded number**: 345900 - **Complete sentence**: 345882 is between 345800 and 345900 and would be rounded up. ### b. 278947 - **Tens digit**: 4 (from 278947) - Since 4 is less than 5, we round down. - **Rounded number**: 278900 - **Complete sentence**: 278947 is between 278900 and 279000 and would be rounded down. ### c. 3489371 - **Tens digit**: 7 (from 3489371) - Since 7 is greater than 5, we round up. - **Rounded number**: 3489400 - **Complete sentence**: 3489371 is between 3489300 and 3489400 and would be rounded up. ### d. 87218965 - **Tens digit**: 6 (from 87218965) - Since 6 is greater than 5, we round up. - **Rounded number**: 87218900 - **Complete sentence**: 87218965 is between 87218900 and 87219000 and would be rounded up. ### Summary of Completed Sentences: a. 345882 is between 345800 and 345900 and would be rounded up. b. 278947 is between 278900 and 279000 and would be rounded down. c. 3489371 is between 3489300 and 3489400 and would be rounded up. d. 87218965 is between 87218900 and 87219000 and would be rounded up.
