NCERT Maths Solution Class 7 Chapter 2 Exercise 2.7 – A Closer Look.
Decimals and fractions serve as the foundation for learning the principles of representing certain Mathematical information with the greatest accuracy feasible. Simply explained, a fraction is a component of something larger, but a decimal is the smallest portion of something mostly uncountable.
Although these images are frequently seen in daily lives, they are not paid much attention to. When Data such as Money, Fluid Amount, Weight, and so on are not complete, they can be represented using Fractions and Decimals. Students can master this chapter by studying with the help of NCERT Solutions For Class 7 Maths Chapter 2 Exercise 2.7.
This chapter’s major insights for students are as follows:
 They can be used interchangeably.
 To convert a Decimal to a Fraction, use the Division Operator.
 To convert a Fraction to a Decimal, use multiplication.
 Further calculations will reveal some additional important elements of employing Decimals and Fractions. They are mentioned below:
 Writing many sorts of Fractions, Including Proper, Improper, and Mixed Fractions.
 Understanding Decimal Numbers (after the decimal).
 Fractional Reciprocity.
 Addition, Multiplication, Subtraction, and Division are Examples of Fraction and Decimal Operations.
 Operations with Fractional Reciprocals

The NCERT Solutions For Class 7 Maths Chapter 2 Exercise 2.7, have been produced by subject specialists to assist students with their test preparations.
Fractions and Decimals are covered in the NCERT Class 7 Maths Chapter 2 Exercise 2.7. In previous lessons, students learned about Fractions and Decimals, as well as the Operations of Addition and Subtraction on them. They are now looking at the Operations of Multiplication and Division on Fractions and Decimals.
Similarly, Multiplication of a Fraction by a Whole Number, Division of a Whole Number by a Fraction, Division of a Fraction by a Whole Number, Multiplication of Decimals by 10,100, 100, and so on. Other themes include Decimal Multiplication by a Whole Number, Decimal Multiplication by a Decimal, Decimal Division by 10, 100, 1000, and so on, and Decimal Division by the Whole Number.
Here is a Brief Overview of All These Questions Covered in This Chapter.
Class 7 Maths Chapter 2 Exercise 2.7 – Question 1
Students are given eight brief questions in the first part, and they must use the Division Operator to determine the number. The first term here is a Decimal, and the second term is a full number. Students must understand how to utilise the Division Operator. In the NCERT Solutions For Class 7 Maths Chapter 2 Exercise 2.7, Extramarks has offered stepbystep solutions to assist students in building a thorough grasp of the concepts and formulas. Students can use the NCERT Solutions For Class 7 Maths Chapter 2 Exercise 2.7, to get a better understanding of these ideas and improve their exam preparation.
NCERT Class 7 Maths Exercise 2.7 – Question 2
The second question is quite similar to the first. They are given seven brief numerical problems to solve using the Division Operator. The only difference between this and the previous question is that the full number here is 10. Students can answer this question using a simple approach found in the NCERT Solutions For Class 7 Maths Chapter 2 Exercise 2.7. When it divides a number with a Decimal by a multiple of 10, it moves the Decimal Place. Students must move that many places to the left of the number containing a Decimal, based on the number of Zeroes in the Divisor.
As previously said, students will discover a Decimal Number in a variety of formats: single or double digits before or after the Decimal. They must use extreme caution while dividing, since even a minor shift in Decimal can result in a false response. As a result, students must ensure that they go through the splitting procedure thoroughly. Students frequently get confused when putting a Decimal point in a number, which is why experts created a stepbystep explanation to help them understand the procedure. The NCERT Solutions For Class 7 Maths Chapter 2 Exercise 2.7, are very useful when it comes to solving questions.
Class 7 Maths Chapter 2 Exercise 2.7 – Question 3
Question 3 requires the Division Operator to employ a Divisor of 100. The only difference between this and the previous question is that students must divide the provided Decimal figures by 100. They are given six short numerical values, each of which contains one or two digits after or before the Decimals.
When working with Decimal Numbers, the most crucial factor to consider is the Decimal Position. It will be easier to approach a question and progress after they have correctly recognised it. The NCERT Solutions for Class 7 Maths Chapter 2 Exercise 2.7, will point them in the proper direction for dealing with these hard issues.
As stated in the preceding question, students must shift the Decimal based on the number of zeroes present. If the number is 100, they must move the Decimal two places to the left. However, there is a crucial tip that they should keep in mind. If there is just one digit before the Decimal and students need to move the Decimal two places to the left, put a ‘0’ (zero) before the Decimal. For example, 4.36 must be divided by 100. In this case, the answer is 0.0436.
Class 7 NCERT Maths Solution Chapter 2 Exercise 2.7 – Question 4
In Question 4, students must use the identical approach of shifting the Decimal as in the previous two problems, except that the Divisor is 1000. That means they must move the Decimal three spaces to the left of its current location. Students can use the NCERT Solutions for Class 7 Maths Chapter 2 Exercise 2.7, to acquire better knowledge and clarity on these concepts. These are conventional answers developed by experts. They are well aware of the grey area where students frequently make mistakes, and they have specifically emphasised such sections. Students will be aware of this in advance, allowing them to avoid making the same mistake in their actual exams.
Students should also use caution when using zero in Decimals. It makes no difference whether students put a zero before or after the Decimal. Placing one or more zeros after the Decimal also does not affect the meaning. Any other zero would result in a different number. For a more indepth explanation, students must refer to the NCERT Solutions for Class 7 Maths Chapter 2 Exercise 2.7.
Class 7 Maths Chapter 2 Exercise 2.7 – Question 5
This is the most crucial question in this exercise because it deals solely with Decimal numbers. Both the Dividend and the Divisor are in Decimal here. Only a thorough comprehension of the topic will enable students to gain a good grasp of it.
Both before and after the Decimal, the numbers have one or two digits. During tests, students sometimes struggle with dealing with numbers in Decimal form. As a result, educators recommend that students convert them into Fractions whenever feasible to simplify the calculation.
In addition, the NCERT Solutions for Class 7 Maths Chapter 2 Exercise 2.7 solutions state that they can convert the division operator to multiplication to make calculations easier. To learn this strategy, students must check the Extramarks study resources before the exam.
NCERT Class 7 Maths Exercise 2.7 – Question 6
This is the final exercise question, and it is a word problem. Students must decide the type of Mathematical operation necessary in this case. They must also comprehend who is to be split by whom.
Students must check out the NCERT Solutions for Class 7 Maths Chapter 2 Exercise 2.7, for more indepth insights on word problems. They must comprehend the primary need for using the division procedure. A car that travels 43.2 kilometres on 2.4 litres of gasoline will go less distance with less fuel. Students can solve this using the unitary technique, which requires them to compute the distance for one litre of gasoline before moving on to larger amounts.
Students must access NCERT Solutions for Class 7 Maths Chapter 2 Exercise 2.7, from the Extramarks website to boost their test preparation. It is also possible to obtain the NCERT Solutions for Class 7 Maths Chapter 2 Exercise 2.7, using that technique if someone already has the Extramarks application downloaded on their phone. The best aspect of the NCERT Solutions for Class 7 Maths Chapter 2 Exercise 2.7, is that it can be used both offline and online.
