**Why 5 is a rational number?**

The **number 5 is a rational number** because we can write it as **5**/1. We can also write it as 15/3 or 50/10 because 15 divided by 3 or 50 divided by 10 both equal **5**. The mixed **number** 1 ½ is also a **rational number** because we can write it as 3/2. Any **number** that can be rewritten as a simple fraction is a **rational number**.

Consequently, is 5 a rational number?

Every integer is a **rational number**, since each integer n can be written in the form n/1. For example **5** = **5**/1 and thus **5** is a **rational number**. However, **numbers** like 1/2, 45454737/2424242, and -3/7 are also **rational**, since they are fractions whose numerator and denominator are integers.

One may also ask, what is a rational number give at least 5 examples? **Examples of rational numbers** are: -2 = -2/1, –**5** = –**5**/1, -14 = -14/1, 1/2, 2/3, **5**/8, 3/4, 17/**5**, . 6 = 6/10 = 3/**5**, . 25 = 1/4, . 33 = 33/100, 2¾ = 11/4, 3? = 10/3, .

Likewise, is negative 5 a rational number?

Answer and Explanation: **Negative 5**, or –**5**, is a **rational number**. **Rational numbers** can be either positive or **negative**. They just need to be the quotient that results when one integer is divided by another.

Is is a rational number?

**Rational Number**. A **rational number** is any **number** that can be expressed as a ratio of two integers (hence the name “**rational**“). For example, 1.5 is **rational** since it can be written as 3/2, 6/4, 9/6 or another fraction or two integers. Pi (π) is irrational since it cannot be written as a fraction.

###
What kind of number is 5?

**5** consists of digits only so it is natural, but as mentioned above it is also integer, rational and real.

###
Is 0 rational or irrational?

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.

###
Is zero a positive integer?

An **integer** is a whole number that can be either greater than 0, called **positive**, or less than 0, called negative. **Zero** is neither **positive** nor negative. Two **integers** that are the same distance from the origin in opposite directions are called opposites.

###
Is 2/5 an irrational number?

Yes. **2/5** is **a rational number**. **A rational number** is a **number** of the form q/q where p and q are integers and q is not equal to 0.

###
Is Pi a rational number?

Only the square roots of square **numbers** are **rational**. Similarly **Pi** (π) is **an irrational number** because it cannot be expressed as a fraction of two whole **numbers** and it has no accurate decimal equivalent. **Pi** is an unending, never repeating decimal, or **an irrational number**.

###
Is Pi a real number?

**Pi** is an irrational **number**, which means that it is a **real number** that cannot be expressed by a simple fraction. When starting off in math, students are introduced to **pi** as a value of 3.14 or 3.14159. Though it is an irrational **number**, some use rational expressions to estimate **pi**, like 22/7 of 333/106.

###
Is 5 a complex number?

**Complex Numbers**. A **complex number** is a **number** of the form a + bi, where i = and a and b are real **numbers**. For example, **5** + 3i, – + 4i, 4.2 – 12i, and – – i are all **complex numbers**. a is called the real part of the **complex number** and bi is called the imaginary part of the **complex number**.

###
Are rational numbers negative?

A **number is** considered a **rational** number if it can be written as one integer divided by another integer. **Rational numbers** can be positive, **negative** or zero. When we write a **negative rational** number, we put the **negative** sign either out in front of the fraction or with the numerator.

###
Why is zero a whole number?

**Zero** does not have a positive or negative value. However, **zero** is considered a **whole number**, which in turn makes it an integer, but not necessarily a natural **number**. **Zero’s** status as a **whole number** and the fact that it is not a negative **number** makes it considered a natural **number** by some mathematicians.

###
Are negative fractions rational?

**Negative fractions** are **rational** numbers – they are not irrational. Any number that can be expressed in the form mn where m,n are integers and n≠0 is a **rational** number. That includes **negative fractions**.

###
Who invented rational numbers?

Pythagoras

###
What kind of number is negative 1?

Integers include all whole numbers and their negative counterpart e.g. … -4, -3, –**2**, -1, **0**,1, **2**, 3, 4,…

###
Is 9 a rational number?

As all natural or whole **numbers**, including **9** , can also be written as fractions p1 they are all **rational numbers**. Hence, **9** is a **rational number**.

###
Is the number 6 an integer?

Then come the “**integers**“, which are zero, the natural **numbers**, and the negatives of the naturals: , –**6**, –5, –4, –3, –2, –1, 0, 1, 2, 3, 4, 5, **6**, The next type of **number** is the “rational”, or fractional, **numbers**, which are technically regarded as ratios (divisions) of **integers**.

###
Is 0 a real number?

Answer and Explanation: Yes, **0** is a **real number** in math. By definition, the **real numbers** consist of all of the **numbers** that make up the **real number** line.

###
