## What to Learn About Decimals?

In Chapter 3, the students will learn how to convert a decimal number into a fraction. Converting a decimal number to a fraction and converting a fractional number into a decimal number is quite easy. The students just need to learn a few simple techniques to convert the decimals into fractional numbers.

### Converting a Decimal Number into a Fractional Number

Suppose you are asked to convert the decimal value of 2.05 into a fractional value. All you have to do is to divide the number by 100 and you will get the result. The simple trick to solve these equations is to count how many numbers are there on the right side of the decimal point.

To get the result you have to write the digits of the decimal number without adding the decimal point as the numerator. If you find that there are two digits at the right of the decimal point then the denominator will be 100 and if there are 3 digits, then the denominator will be 1000. Now, you have to simplify the fraction to get the answer.

In the above-mentioned case, the answer will be 205/100=41/20. YOu can further simplify the equation and you will get a mixed fraction as the result.

### Converting a Fractional Value into a Decimal Value

To do so, you need to simplify the fractional value with the help of division and multiplication until you get the decimal value. If you have to convert the value of a mixed fraction, then you have to multiply the whole number with the denominator and then add the numerator to get the final fractional value that you can convert into a decimal number. You will get a detailed analysis of these simple equation processes in the RS Aggarwal Solutions.

## FAQs on RS Aggarwal Solutions Class 7 Chapter-3 Decimals (Ex 3E) Exercise 3.5 - Free PDF

1. Why should the students consider consulting RS Aggarwal Solutions for Decimals preparation?

About the learning process, the students need to get their hands on something that can guide them in the right direction and explain the intricacies of solving and answering a particular question. When it comes to Mathematics, there is a possibility that you can make errors unknowingly while carrying out a calculation process. Rs Aggarwal Solutions make sure that the students can verify their own answers with the answers provided in the solved papers.

While solving the Mathematical equations the students often make minor mistakes while calculating and as a result, they get faulty answers. Sometimes students also make errors in the sequential steps of the calculation procedure. Consulting these reference books will give them a better idea of how to write the equations one by one and make the calculations in the correct manner.

2. What is the significance of learning the concepts and equations of decimals?

This particular number system helps people to be more precise and represent a particular numerical value in an accurate manner while referring to the length, weight or any quantity of a particular object. We often use whole numbers to signify a specific amount of something, but when it comes to being more precise at giving an idea of a particular amount of quantity, we have to make use of the decimal number system.

3. Why do the students need to be more attentive while handling the decimal numbers?

Making use of the decimal number system makes your task easier and helps you in referring to a particular amount in the most accurate manner. But there is a chance to make minor mistakes that can result in a drastically wrong estimation of a numerical value. Since students cannot use calculators to find out the answer to the questions, they need to be very attentive while placing the decimal point, as placing the decimal point somewhere else other than the correct place, can provide you with an entirely wrong answer.

4. Where can the students get access to RS Aggarwal Solutions for Class 7 in order to understand the concept of decimals?

The students can easily download the various Chapters of RS Aggarwal Solutions from the website of Vedantu. On the website of Vedantu, the students will get solved question papers for each Chapter so that they can focus individually on each of the Chapters and practice the equations and calculations one by one to score better in the examination. Also, on the website of Vedantu, there are revision notes available that will further assist them in revising their concepts and practice papers.
