Question

Whole numbers are a type of rational numbers. All whole numbers are rational numbers, but not all rational numbers are whole numbers. Whole numbers are positive integers and zero, while rational numbers can be expressed as a fraction of two integers. For example, the whole number 7 can be written as 7/1, making it a valid rational number.

Answer 1

This definition is incorrect. While it is true that all whole numbers are rational numbers, it is not accurate to state that all rational numbers can be expressed as a fraction of two integers. In fact, rational numbers can be expressed as a fraction of two integers, where the denominator is not zero. This includes all integers (including whole numbers) and fractions. However, it also includes repeating decimals and terminating decimals, which cannot be expressed as a fraction but are still considered rational numbers.
