  • Rational numbers are numbers expressible as a fraction (a/b) where a and b are integers (whole numbers), with b ≠ 0 (denominator cannot be zero).

  • This exercise will introduce you to the concept of additive inverses. 

  • The additive inverse of a number is the number you add to it to get zero. For example, 5 and -5 are additive inverses because 5 + (-5) = 0.

  • In Class 8 Maths Chapter 1 Exercise 1.1 Solutions PDF questions might ask you to verify properties that hold for rational numbers. Examples include the commutative property for addition (a + b = b + a) or the associative property for addition (a + (b + c) = (a + b) + c).

Exercise 1.1

1. Name the property under multiplication used in each of the following:

i. $\dfrac{-4}{5}\times 1=1\times\dfrac{-4}{5}=\dfrac{-4}{5}$

Ans: Since, after multiplying by 1, we are getting the same number.

Therefore, 1 is the multiplicative identity.


ii.$-\dfrac{13}{17}\times \dfrac{-2}{7}=\dfrac{-2}{7}\times\dfrac{-13}{17}$

Ans: Since, $a\times b = b\times a$.

Therefore, it is a Commutative property.


iii. $\dfrac{-19}{29}\times \dfrac{29}{-19}=1$

Ans: Since, $-a\times \dfrac{1}{-a}=1$

Therefore, the property is a Multiplicative inverse.


2. Tell what property allows you to compute 

$\dfrac{1}{3}\times(6 \times \dfrac{4}{3})$ as $(\dfrac{1}{3}\times 6)\times \dfrac{4}{3} $

Ans: Since, $a\times(b\times c)= (a \times b)\times c$.

Therefore, it's an associative property.


3. The product of two rational numbers is always a __________.

Ans: The product of two rational numbers is always a Rational number.


Conclusion

NCERT Solutions for Class 8 Maths Chapter 1 Exercise 1.1 Solution PDF of Rational Numbers, focuses on essential concepts such as equivalent rational numbers, their simplification, and representation on a number line.
