Question

What is $\dfrac{1}{5}$ as a whole number?

Answer 1

Hint: We need to write $\dfrac{1}{5}$ as a whole number. The whole numbers are the positive integers that include numbers from zero to infinity. This number does not include any fractional or decimal parts.

Complete step by step solution:
The whole numbers are the numbers that include all the positive integers and zero. It does not include negative integers and fractions. They are also called the basic counting numbers.
A fraction, in mathematics, represents a part of a whole thing. It consists of two parts namely,
numerator, denominator.
The number on the top is called the numerator.
The number on the bottom is called the denominator.
Let us understand the concept of the fraction with an example as follows,
Example:
$\Rightarrow \dfrac{a}{b}$
In the above fraction,
$a$ is the numerator of the fraction
$b$ is the denominator of the fraction
According to our question,
We need to express the fraction $\dfrac{1}{5}$ as a whole number.
The fraction $\dfrac{1}{5}$ means 1 part of 5 equal parts in which the whole is divided.
In the given fraction,
1 is the numerator
5 is the denominator
$\dfrac{1}{5}$ is not a whole number. So, it cannot be changed or written as a whole number. The fraction can be only expressed in the form of percentage and decimal.
A percentage is a value expressed as a fraction of a hundred or $\dfrac{1}{100}$ . It is denoted by the symbol
 ’$\%\;$’. The value expressed as a percentage does not have any dimension or unit of measurement.
For Example:
$\Rightarrow 2\%,3\%$
The fraction $\dfrac{1}{5}$ can be expressed as a percentage by simply multiplying it by 100.
Applying the same,
$\Rightarrow \dfrac{1}{5}\times 100\%$
$\Rightarrow 20\%$
$\therefore \dfrac{1}{5}=20\%$
The fraction $\dfrac{1}{5}$ can be expressed in decimal by simply dividing the number 1 with 5.
$\Rightarrow \dfrac{1}{5}=0.2$

Note: Whole numbers are the basic counting numbers starting from the number 0. A fraction represents a part of a whole. We must always remember that a fraction cannot be expressed or changed as a whole number.
