Explanation:

We have the number 3,8763,876 and we want to round it to the nearest hundred.

In order to round it to the nearest hundred, though, let's go over some rules...
1) If the number is more than 5050, then you round up. If the number is less than 5050, then you round down.

In this case, the 7676 in 3,8763,876 is more than 5050, so 3,8763,876
rounded to the nearest hundred is 3,9003,900
