## Fraction and Decimals Class 7 Exercise 2.4 â€“ In a Nutshell

Fractions and decimals are the fundamentals of the number system, and they form a basis for understanding how to represent the portions of anything that are not whole. These are used in our daily life but are often overlooked. We do not realise the times and areas where we use fractions and decimals, starting from money, weight to length and many more.

Decimals are mainly used to define precision, and fractions are used to represent a part of something. Students should know that both of these are interchangeable. All you have to do is either divide or multiply to get the other one, based on the requirement.

You can clear such concepts from our NCERT Solutions for Class 7 Maths Chapter 2 Exercise 2.4 in the most straightforward manner. We have jotted down all the essential pointers that a student should consider before going deeper into this topic. Also, we have provided a tabular representation for the tips and tricks that might be helpful for you to solve these problems.

In this chapter, you are likely to learn about:

How to write decimals along with whole numbers

How to write fractions

Reciprocal of fractions

Types of fractions â€“ regular, improper, mixed

Mathematical operations using fractions and decimals

For a comprehensive analysis of all the pointers mentioned above, you can refer to our Maths NCERT Solutions Class 7 Chapter 2 Exercise 2.4; it will help you in understanding the concepts from the grassroots as well as in improvising your learning pattern. Here is a brief description of the questions covered in this exercise.

Exercise 2.4 Class 7th â€“ Question 1

In this first question, you are asked to work on mathematical operators like addition and division on six short questions present under it. The critical part of these questions is that you have to perform the addition or division between a whole number and a fraction.

Take a look at our NCERT Solutions for Class 7 Maths Chapter 2 Exercise 2.4 offered by Vedantu, where we have tried to simplify the process for you. Students can take help for the shortcut tips that we have listed based on these types of numerical.

You should have a clear understanding of:

Converting each term into similar fractions before using an operator between them.

Basics clarity of proper and improper fractions.

Addition and multiplication are used during the increment of something.

Subtraction and division are used for decrement.

Understanding these fundamentals is crucial as it will help you in handling advanced level sums too. Also, you can streamline your studying pattern in the right direction. As a result, you can gain an extra edge in the competition prevalent in exams too.

Ex 2.4 Class 7 Maths â€“ Question 2

In the second question, you are asked to find the reciprocals of each fraction given. Seven fractions are provided, and you have to classify them as well. While you study for fractions from our NCERT Solutions for Class 7 Maths Chapter 2 Exercise 2.4, you will be aware that:

In a fraction, a bar divides two numbers, irrespective of the number of digits in them.

The number written over the bar is called numerator.

The denominator is the number written under the bar.

So, when you are asked to find the reciprocal, it is simply interchanging their places, irrespective whether it is a proper fraction or not. Further, students should also be aware of the types of fractions and their properties, such that:

A proper fraction: Numerator < denominator

An improper fraction: Numerator > denominator

Mixed fraction: Whole number and fraction together (fraction can be either proper or improper)

Make sure you revise these pointers carefully presented in our NCERT Solution for Class 7 Maths Chapter 2 Exercise 2.4. It will assist you in developing a firm hold on the fundamentals of fractions and decimals.

Exercise 2.4 Class 7 â€“ Question 3

Question 3 is similar to the first question; the only difference is that here the first term is a fraction and a second term is a whole number. It is unlike the previous question, where the first term was a whole number and the second was a fraction.

Although the operators remain similar â€“ either addition or division - students often tend to get confused between these. Hence, we recommend you to go through our NCERT Solutions for Class 7 Maths Chapter 2 Exercise 2.4 to gain clarity on such crucial pointers.

The procedure for operating remains the same, as you convert the whole number into a fraction by:

Either adding a denominator 1 to the whole number.

Follow the essential addition of a whole number to a fraction.

You can choose to perform either of the methods mentioned above. However, make sure you do them correctly. Having a sound knowledge of fractions will help you to ace this section easily. Take help from our study materials for CBSE Class 7 Maths Chapter 2 Exercise 2.4 to redirect your learning in the right direction.

Exercise 2.4 Class 7 Maths â€“ Question 4

Contrary to the previous questions, here you are given eight short questions that contain two terms each. Each term is a fraction, and you have to perform either addition or division with those, as per requirement.

Students should understand that the process of conducting the operation is the same as the previous ones. However, they should be careful when:

The denominators are different for two terms.

One of the denominators is not a factor of the other.

The numbers do not have immediate multiple.

In such cases, the denominators should be multiplied to each other. Go through our NCERT Solutions for Class 7 Maths Chapter 2 Exercise 2.4 and get to know these short tricks as and when required.

It is essential to know when and how should you approach a particular question. To get thorough with such usage, you need to practise the sums regularly. It will not only create a learning environment for you but also keep you ready to face any twisted question during the actual exam.
