That would be the second option.

There is no number which is less than 1 and greater than 1.

Answer:

{x | x < 1} and {x | x > 1}

Step-by-step explanation:

{x | x ≤ 1} and {x | x ≥ 1}

'And ' means the intersection of two inequalities

In both inequalities , we have 1 in common . So solution is 1

{x | x < 1} and {x | x > 1}

In both inequalities , there is no number in common because we have x<1 and x>1. there is no intersection for both inequalities. So, No solution.

{x | x ≤ 1} or {x | x ≥ 1}

For 'or', the solution is the combination of both inequalities. So there is a solution.
