Question

(i) Write the set Q of rational number using rule method​

Answer 1

Answer:

Set Q of rational number in the property form is given by :

\bf Q=\{\frac{b}{c}:\textbf{ b, c }\in Z\textbf{ and c }\neq 0\}Q={

c

b

: b, c ∈Z and c



=0}

Step-by-step explanation:

The numbers that can be expressed in the form of fraction : b by c such that b cannot be 0 , b and c both are integers are called rational numbers.

Hence the set Q of rational numbers in the property form can be expressed in the given form :

\bf Q=\{\frac{b}{c}:\textbf{ b, c }\in Z\textbf{ and c }\neq 0\}Q={

c

b

: b, c ∈Z and c



=0}

Hence,the above representation of the set of rational numbers Q is called the property form or the set builder notation of Q.
