Answer 1

Answer:

We will learn about the positive rational number.

A rational number is said to be positive if its numerator and denominator are either both positive integers or both negative integers.

In other words, a rational number is positive, if its numerator and denominator are of the same sign.

Each of the rational numbers 1/4, 2/9, -7/-11, -3/-13, 5/12 are positive rationals, but 2/-5, -3/10, -4/7, 11/-23 are not positive rationals.
