NCERT Solutions for Class 7 Maths Chapter 9 Rational Numbers

 

NCERT Solutions for Class 7 Maths Chapter 9 Rational Numbers: In our earlier classes we have studied about whole numbers which include the counting numbers0, 1, 2, 3....... and the natural numbers ( positive integers) which include 1, 2, ...... and also fractions and integers. Integers includes ........-2 ,-1, 0, 1, 2, 3 .............. Fractions are the numbers of the form \frac{p}{q} where p and q are positive integers and q cannot be zero. In NCERT Solutions for Class 7 Maths Chapter 9, we will study a new number system known as rational numbers. The NCERT Solutions provided by our experts are easy to understand.

What are rational numbers?

The numbers of the form p/q where q\neq0  and p and q are integers is known as rational numbers. All integers are also rational numbers. That is -3 can be written as -3/1. 

What is the difference between a fraction and a rational number?

The difference between a fraction and a rational number is fractions contains only positive integers whereas the rational number contains positive and negative integers. Thus rational numbers include both integers and fractions. All fractions are rational numbers but all rational numbers are not fractions. That is -3 is not a fraction since -3 is a negative integer but -3 is a rational number.

Is zero a rational number?

Yes, zero is a rational number. 0 can be written as 0/1 or 0/2 or 0/3 .......which is of the form p/q where q not equal to zero.
