NCERT Solutions Class 7 Maths Chapter 9 Rational Numbers
Arithmetic starts when we start referring to things around us in terms of numbers. The numbers that we generally use for counting objects around us are called counting or natural numbers. Including a zero gives rise to the whole numbers while including the negatives to integers. The NCERT solutions for class 7 maths chapter 9 Rational Numbers start with these basics as to how the number system got expanded from the natural to the whole numbers and then to integers. This chapter takes the number system further to rational numbers and how the arithmetic operations are dealt with rational numbers. The students will learn that at times few quantities need to be represented by a value that is neither an integer nor it comes under the category of fraction; hence a category of rational number was made for such values. Also, the term rational number takes its origin from the word ‘Ratio'.
Hence, from the NCERT solutions class 7 maths chapter 9 Rational Numbers, students must remember the basic definition of rational numbers, which says rational numbers are those that can be written in the form of a/b, where ‘a’ and ‘b’ are integers, and b is not equal to zero. For more information on rational numbers, the class 7 maths NCERT solutions chapter 9 Rational Numbers can be downloaded from the link below, and also find some of these in the exercises given below.
