A **real number that is not rational** is called irrational. Irrational **numbers** include √2, π, e, and φ. The decimal expansion of **an irrational number** continues without repeating.

Secondly, is 7 a rational number? **Rational Numbers**. Any **number** that can be written as a fraction with integers is called a **rational number** . For example, 1**7** and −34 are **rational numbers**.

In respect to this, what is the difference between a real number and a rational number?

Explanation: **Rational** are those **numbers** which can be written as a ratio of two integers, the denominator being non-zero. **Real numbers** are those, which can be represented on **real number** line. Hence, though all **rational numbers** are **real numbers**, there are some **numbers** (irrational **numbers**) which are not **rational numbers**.

Is 0 rational or irrational?

Any number which doesnt fulfill the above conditions is **irrational**. What about **zero**? It can be represented as a ratio of two integers as well as ratio of itself and an **irrational** number such that **zero** is not dividend in any case. People say that 0 is **rational** because it is an integer.
