Identifying Rational and Irrational Numbers by Decimal Form

A retail manager is calculating the discount rate for a clearance sale and finds the value can be expressed as a ratio of two integers, such as 1/4. What is the mathematical term for any number that can be written in the form 'p/q', where p and q are integers and q is not zero?

A quality control technician records a measurement as 0.375. Because this decimal terminates and can be written as a ratio of two integers, it is classified as a(n) ____ number.

In a quality control report, a technician identifies a measurement that can be written in the form p/q, where p and q are integers and q is not zero. This measurement is mathematically classified as a rational number.

In a corporate accounting workshop, you are reviewing the classification of numerical data used in financial reports. Match each term related to rational numbers with its correct mathematical characteristic or example based on the definitions used in your training.
