# Is negative 7 rational?

**negative 7**(-

**7**) is a

**rational**number because -

**7**satisfies the definition of a

**rational**number. Other examples of

**rational**numbers are: 1/2, 3/4, 22/

**7**, 5 = 5/1, 2½ = 5/2, 0 = 0/1, .

Keeping this in view, are negative numbers rational?

The **rational numbers** includes all positive **numbers**, **negative numbers** and zero that can be written as a ratio (fraction) of one **number** over another. Whole **numbers**, **integers**, fractions, terminating decimals and repeating decimals are all **rational numbers**.

**1**is an integer (the

**negative**of a natural

**number**). All integers are rational. So an

**irrational number**is a

**number**that cannot be expressed as the quotient of two integers. To prove a

**number irrational**, you must prove the impossibility of expressing it as the quotient of two integers.

In respect to this, is negative 3 a rational number?

−**3 is negative** so it is not a natural or whole **number**. **Rational numbers** are **numbers** that can be expressed as a fraction or ratio of two integers. **Rational numbers** are denoted Q . Since −**3** can be written as −**3**1 , it could be argued that −**3** is also a real **number**.

Any number which doesn't 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.
