In mathematics, the natural numbers are those numbers that are used for counting and ordering. They start from 1 and include all positive integers upto infinity.
Since, 102 and 112 are both positive integers, then they both also qualify as natural numbers and so should the numbers between them which also are positive integers. We will have to count the number of natural numbers thus present in between 102 and 112 to obtain our desired answer.
The numbers between 102 and 112 are 103,104,105,106,107,108,109,110 and 111 .
Since all of these are positive integers and belong to the set or range of ( 1 to Infinity), they are natural numbers. Hence, there are 9 natural numbers between 102 and 112 .
