In this post we will learn how to divide fraction by whole number with simple steps.
After that we will move on to solve some questions related to the concept.
I urge all the students to take out pencil and paper and start learning by writing.
What happen when fraction is divided by whole number?
Here we will understand what will happen to the fraction when we divide it by a whole number.
Given below is a rectangle which is divided into 2 parts (i.e. fraction \frac{1}{2} )
Now divide the fraction \frac{1}{2} with whole number 3
It means that the half part of rectangle is divided into 3 parts
After division the rectangle would look like this:
After calculating the division we get:
Now the solution is \frac{1}{6} of the rectangle
Hence after dividing the fraction with whole number, we have made the fraction smaller
How to divide Fraction by Whole Number
Suppose one fraction and whole number is given.
And you have to divide the whole number
You can do the division by following below steps
Step 01
Convert the whole number into fraction by putting denominator 1
Step 02
Convert the division into multiplication by inversing digits of the right fraction
Step 03
Multiply the numerators of both fractions
Step 04
Multiply the denominators of both fractions
Step 05
If possible reduce the numerator and denominator to its lowest terms
I hope the process is clear.
Let us practice the division concept with the help of examples.
Example 01
Divide the given fraction and whole number
Do the following steps
Step 01

Step 03
Multiply the numerator and denominator separately
Step 04
Reduce the fraction to lowest level
The resultant fraction now cannot be further divided.
Hence \frac{4}{21} is the solution
Example 02
Divide the below fraction and the whole number
Do the following steps
Step 01
