There is only one type of rational number so there are no different types which you can add.
Natural numbers Integers Rational numbers Real numbers Complex numbers
In their rational form, the denominators have factors other than 2 and 5.
You can multiply any pair of rational numbers as well as any irrational number and its reciprocal (or a rational multiple of its reciprocal. Thus pi * 3/7*(1/pi) is rational.
There is only one type of rational number, namely the type that follow the definition precisely: A rational number is a number that can be written as a fraction of two (relatively prime) whole numbers a and b. A number is either rational or not rational. 123/67 is a rational number. Pi, or the square root of six, are irrational numbers. In decimal form, a rational number has a finite amount of decimals, or a repeating pattern of them. An irrational number has infinitely many non-repeating decimals.

There are infinitely many rational numbers and, in decimal form, most of them have infinitely many digits. So there cannot be a longest rational number.
