Answer:
1,100
Step-by-step explanation: The hundreds place is the second 1 from the left. That number will stay as it is or go up one number, based on the number to its right, which in this case is a 3. If the 3 is the number 5 or larger, then the 1 would round up to a 2, but since the 3 is less than 5, the 1 stays a 1. All numbers to the right of the place value you are rounding to become zeros.
