Because the first three operations close the set of integers:
Add
Subtract
Multiply
These operations will return a set of integers as a result.
When you divide two numbers, though, the result is when the first and second integers are not multiples of each other (In other words, when the second integer is not a factor of the first integer), Then, rather than an integer, the outcome will be the Ratio between the two integers.
Hence the term “rational” for such numbers.
Finally, we concluded that when we add, subtract, and multiply will return a set of integers as a result. and when we divide integers the outcome will be the Ratio between the two integers. Hence the term “rational” for such numbers.
