Question

When you add two rational numbers, each number can be written as a?

Answer 1

The correct answer to your question is... a rational #, because when you add two rational #'s, each # can be written as a rational #. 

Reasoning:
So, adding two rational #'s like adding fractions will result in another fraction of this same form since integers are closed under + and x. Thus, adding two rational #'s produces another rational #.

By the way # means number.
