NCERT Solutions for Class 7 Maths Chapter 9 Rational Numbers

Exercise 9.1

1. List five rational numbers between:
(i) -1 and 0
(ii) -2 and - 1
(iii) -4/5 and -2/3
(iv) -1/2 and 2/3

Answer

(i) -1 and 0
Let us write -1 and 0 as rational numbers with denominator 6.
Therefore, five rational numbers between -1 and 0 would be

(ii) -2 and -1
Let us write -2 and -1 as rational numbers with denominator 6.
Therefore, Five rational numbers between -2 and -1 would be

(iii) -4/5 and -2/3
Let us write -4/5 and -2/3 as rational numbers with the same denominators.
Therefore, five rational numbers between -4/5 and -2/3 would be

(iv) -1/2 and 2/3
Let us write -1/2 and 2/3 as rational numbers with the same denominators.
Therefore, five rational numbers between -1/2 and 2/3 would be

2. Write four more rational numbers in each of the following patterns:
Answer

Therefore, four equivalent rational numbers are

(ii) 
Therefore, the next four rational numbers of this pattern would be

(iii) 
Therefore, the next four rational numbers of this pattern would be

(iv) 
Therefore, the next four rational numbers of tins pattern would be

3. Give four rational numbers equivalent to:
(i) -2/7
(ii) 5/-3
(iii) 4/9
(iv) -2/7

Answer

(i)
Therefore, four equivalent rational numbers are

(ii) 5/-3
Therefore, four equivalent rational numbers are

(iii) 4/9
Therefore, four equivalent rational numbers are

4. Draw the number line and represent the following rational numbers on it: 
(i) 3/4
(ii) -5/8

NCERT Solutions for Class 7 Maths Chapter 9 Rational Numbers


In Chapter 7 Maths NCERT Solutions, we will deal with rational numbers which is defined as a number that can be expressed in the form p/q , where p and q are integers and q ≠ 0. All numbers, including whole numbers, integers, fractions and decimal numbers, can be written in the numerator-denominator form.

• The rational number zero is neither negative nor positive. Positive rational numbers are represented to the right of 0. Negative rational numbers are represented to the left of 0.

• A rational number is said to be in its standard form if its numerator and denominator have no common factor other than 1, and its denominator is a positive integer.

How to do addition of rational numbers?



• If the denominators of the given rational numbers are the same, then the denominator of their sum will also be the same. The numerator of the sum of two rational numbers with the same denominator is the sum of the numerators of the given numbers.
• To add rational numbers with different denominators, we convert them into equivalent rational numbers with the same denominator.
• Two rational numbers whose sum is zero are called additive inverses of each other.

How to do multiplication of rational numbers?



• To multiply two rational numbers, we simply multiply their numerators and denominators with their correct signs.
• Two rational numbers whose product is 1 are called reciprocals of each other.
• A rational number and its reciprocal will always have the same sign.
