Answer 2

Answer:

Step-by-step explanation:

Natural numbers are the numbers which start from 1 to infinity.

As it is between 111 and 999, we shouldn’t include 111 and 999 and consider rest all the numbers between 111 and 999.

So the no of numbers between 111 and 999=999-112 =987

Therefore, Answer= 987
