## What is classification of numbers?

The

**classifications of numbers**are: real**number**, imaginary**numbers**, irrational**number**, integers, whole**numbers**, and natural**numbers**. Rational**numbers**are any**number**that can be written as a fraction. Irrational**numbers**are**numbers**that cannot be written as a fraction and include never-ending decimal**numbers**, like π.## What type of number is 7?

Natural

**Numbers**– the set of**numbers**, 1, 2, 3, 4, 5, 6,**7**, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17,.., that we see and use every day. The natural**numbers**are often referred to as the counting**numbers**and the positive integers.## What are the types of real numbers?

The set of

**real numbers**consist of**different**categories, such as natural and whole**numbers**, integers, rational and irrational**numbers**. In the table given below, all these**numbers**are defined with examples. Contain all counting**numbers**which start from 1.## How do you classify real numbers?

As we saw with integers, the

**real numbers**can be divided into three subsets: negative**real numbers**, zero, and positive**real numbers**. Each subset includes fractions, decimals, and irrational**numbers**according to their algebraic sign (+ or –). Zero is considered neither positive nor negative.## Is 21 a real number?

Therefore

**21**≠a2 , so a≠√**21**, meaning that our earlier assumption of √**21**being rational turns out to be wrong, therefore √**21**is irrational.## Is 0 a real number?

**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.## Is the square root of 36 a real number?

The

**square root of 36**is a**rational number**. A**rational number**is a**number**that can be written as a fraction, a/b, where a and b are integers.## What is the root number of 36?

Thus, the square

**root**of**36**is 6.## Is 5 a whole number?

In mathematics,

**whole numbers**are the basic counting**numbers**0, 1, 2, 3, 4,**5**, 6, … and so on. 17, 99, 267, 8107 and 999999999 are examples of**whole numbers**.**Whole numbers**include natural**numbers**that begin from 1 onwards.## Is 36 a whole number?

The first 100

**whole numbers**are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25,26, 27, 28, 29, 30, 31, 32, 33, 34, 35,**36**, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74,## What is the smallest whole number?

The

**smallest whole number**is “0” (ZERO).## How many whole numbers are there between 17 and 22?
