An Introduction to Fractions and Mixed Fractions

In Mathematics, fraction is used to show or represent a part of the entire thing. It can represent things as equal parts of the whole. In the representation of fractions, there are two parts namely numerator and denominator.

The number written on the top is known as the numerator. The number written on the bottom part is known as the denominator. The number of equal parts of a thing written on top is called the numerator. The denominator is the whole number in a fraction.

If 510 is a fraction.


The number 5 is a numerator, and 10 is a denominator.

Improper Fraction

The fractions in which the numerator value is larger than the denominator are known as improper fractions.

E.g. 73,95,72


Mixed Fraction

It can be defined as the fraction made up of a combination of whole numbers and fractions.

e.g. 312,512


How to Convert an Improper Fraction into a Mixed Fraction?

There are certain steps to convert an improper fraction into a mixed fraction. These are discussed below.

First Step: We need to identify the improper fraction.

Second Step: Then, we need to divide the numerator by the denominator and thereby obtain the quotient and remainder.

Third Step: Now, the mixed fraction can be written as:

Quotient (Remainder/Denominator).


Simple Way to Convert Improper Fraction to Mixed Fraction

To convert an improper fraction to a mixed fraction, divide the numerator (upper portion) by the denominator in order to write an improper fraction as a mixed fraction (bottom part). The numerator is the remainder, and the quotient is the entire number.


Solved Examples

Example 1. Let us convert 75 into a mixed fraction.

Ans: If in a fraction the numerator and denominator have the same number, it will make a whole.

In the case of 75,55 can be extracted and that can be made a whole.

Therefore, the remaining fraction is 2/5.

So, now we can write 75 as the mixed fraction, and that is 125

The fraction 75 means that 7÷5. Now we divide 7 by 5 and get 1 as the quotient making 2 as the remainder.

In order to convert an improper fraction into a mixed fraction, we need to use the quotient 1 as the whole number and the remainder 2 as the numerator whereas the divisor 5 is used as the denominator of the proper fraction.

Example 2. Convert the improper fractions into mixed fractions:

(i) 174

Ans: According to the question, the numerator is 17, and the denominator is 4

In order to convert the improper fraction into a mixed fraction, we divide the numerator with the denominator.

When we divide 17 by 4

Quotient = 4, Remainder = 1, Denominator = 4.

Hence, 174=414


(ii) 135

Ans: According to the question, the numerator is 13, and the denominator is 5

In order to convert the improper fraction into a mixed fraction.

We divide the numerator with the denominator.

When we divide 13 by 5

Quotient = 2, Remainder = 3, Denominator = 5.

Hence, 135=235


(iii) 285

Ans: According to the question, the numerator is 28, and the denominator is 5

In order to convert the improper fraction into a mixed fraction.

We divide the numerator with the denominator.

When we divide 28 by 5

Therefore, Quotient = 5, Remainder = 3, Denominator = 5

Hence, 285=535


(iv) 289

Ans: According to the question, the numerator is 28 and the denominator is 9

In order to convert the improper fraction into a mixed fraction.

We divide the numerator with the denominator.

When we divide 28 by 9

The Quotient = 3, Remainder = 1, Denominator = 9.

Hence, 289=319


Practice Questions

Convert the following improper fractions into mixed fractions.


Q 1. Convert into mixed fractions:

(a) 73

(b) 117

(c) 136

Ans: (a) 213

(b) 147

(c) 216


Q 2. Write improper fraction of 39

Ans: 13


Summary

Fractions are representations of a single part out of many parts, and they can be in different forms either mixed or improper. Fractions can be converted into either form following a few steps. The steps include identifying an improper fraction, dividing the numerator by the denominator to get a quotient and remainder, and finally, the mixed fraction is written as Quotient (Remainder/Denominator).

Fractions are very useful in expressing a lot of things such as time, i.e. every minute is a part of an hour and every hour is a part of a day.

FAQs on Conversion of Improper Fractions Into Mixed Fractions

1. What is the need to convert an improper fraction into a mixed fraction? 

Improper fractions need to be converted to mixed fractions because improper fractions are those in which the numerator value exceeds the denominator. A mixed fraction is one that combines both whole numbers and fractions. The primary purpose of this conversion procedure is to streamline calculations that call for incorrect fractions. But since mixed fractions are simpler to understand, we can use them to describe a result.

2. Convert an improper fraction into mixed fraction 358

According to the question, the numerator is 35 and the denominator is 8.

In order to convert the improper fraction into a mixed fraction. 

We divide the numerator with the denominator. 

When we divide 35 by 8 , the Quotient = 4, Remainder = 3, Denominator = 8.

Hence, the final result is 358=438

3. Can mixed fractions be used in arithmetic operations? 

Mixed fractions are those fractions in which a whole number is combined with a fraction. The mixed fractions can also be added, subtracted, multiplied or divided just like the integers. They need to be converted into a suitable improper fraction first and that makes the process easier to obtain. Thereafter, the operation processes are very similar to normal integer operation.
