1. 9886, round to the nearest hundred.

When rounding 9886 to the nearest hundred, look in the ten’s column and remember that if the number is 5 or greater, you add one to the hundred’s column. 8 is, so 9886 is now 9906. The 6 is also greater than 5, so that would make the hundred’s column a 9, which is still greater than 5, and still making the hundred’s column a 9.

ANSWER: 9900
