861 ≈ 900

900

Step-by-step explanation:

Since you are doing it to the nearest 100, you look at the ten's place.

If the number is higher then 5, you round up

If its lower, you round it to the digit already in the hundreds place.

In the question, the digit is 6, which means it will be rounded up

so instead of 800, it would be 900
