Solución
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.
