If Q= $open curly brackets x colon x equals fraction numerator 1 over denominator y end fraction comma text where end text y element of N close curly brackets comma text end text$ then-

Hence, $1 element of Q$ is correct.

If Q= $open curly brackets x colon x equals fraction numerator 1 over denominator y end fraction comma text where end text y element of N close curly brackets comma text end text$ then-

Hence, $1 element of Q$ is correct.

Let A $equals left curly bracket x colon x element of R comma vertical line x vertical line less than 1 right curly bracket comma B equals left curly bracket x colon x element of R comma vertical line x minus 1 vertical line greater or equal than 1 right curly bracket text end text$ and $A union B$ =R-D, then the set D is

Therefore, set of D is $left curly bracket x colon 1 less or equal than x less than 2 right curly bracket$ .

Let A $equals left curly bracket x colon x element of R comma vertical line x vertical line less than 1 right curly bracket comma B equals left curly bracket x colon x element of R comma vertical line x minus 1 vertical line greater or equal than 1 right curly bracket text end text$ and $A union B$ =R-D, then the set D is

Therefore, set of D is $left curly bracket x colon 1 less or equal than x less than 2 right curly bracket$ .
