Question

is every rational number is a whole number

Answer 1

Every whole number is a rational number: for example, 3 . So it isrational. Every whole number n can be written as a fraction of integers: n . We aren't required to write it that way; we just need to know that it is possible to express every whole number as a fraction of integers, and hence it isrational.

Answer 2

NO Rational number consists of all integers and all fractional numbers whereas whole numbers do not contain negative integers.
