Question

How is a rational number that is not an integer different from a rational number that is an integer

Answer 1

All numbers are rational numbers. if its a fraction, decimal, whole number, etc..

But integers are only consist of negative and positive numbers

Answer 2

Each integer is rational number, but each rational number is not integer.

Explanation:

We are asked to determine how a rational number that is not an integer different from a rational number that is an integer.

We know that an integer is a whole number. It can be positive or negative. We can write any integer as a fraction by writing 1 in denominator. For example 5 is an integer. We can write it as a fraction
`5=(5)/(1)`.

Another example is
`-7=(-7)/(1)` is an integer.

We know that a number is rational, when it can be written as fraction. For example
`(2)/(3)`, but it is not an integer.

Another example is
`(15)/(3)=5` is an integer.

Therefore, each integer is rational number, but each rational number is not integer.
