Question

sortly explain why are whole numbers rational use 15 as a examplle

Answer 1

A rational number is any number that can be written as a fraction a/b where a and b are integers and b ≠ 0. Whole numbers are integers, so any whole number n = n/1, which fits that definition.

Example: 15 = 15/1 (or 30/2, 150/10, etc.), so 15 is rational.
