A number which can be written in the form p/q where p and q relatively prime integers and q =0 is called as

Answer 1

If your question means:

A number which can be written in the form p / q where p and q relatively prime integers and q ≠ 0

then

Two integers are relatively prime when there are no common factors other than 1.

A rational number is a number that can be expressed as a fraction p / q of two integers, a numerator p and a non-zero denominator q.

So p / q where p and q relatively prime integers and q ≠ 0 is called as a rational number.
