Question

How do you know ik a number is a rational number?​

Answer 1

Step-by-step explanation:

Any number that can be written as a fraction or a ratio is a rational number. The product of any two rational numbers is therefore a rational number, because it too may be expressed as a fraction. For example, 5/7 and 13/120 are both rational numbers, and their product, 65/840, is also a rational number.

Answer 2

Answer:

If a number can be represented in the form p/q or as a fraction where p and q are coming prime integers (common factor 1) and q is not equal to 0.

Rational numbers are either terminating or repeating.
