The set of real numbers less than 5 is represented as ((-∞, 5)). This interval includes all numbers from negative infinity up to, but not including, 5. It encompasses all rational and Irrational Numbers that fall below 5. In set notation, it can be described as ( { x \in \mathbb{R} \mid x < 5 } ).
Infinite
In a certain sense, the set of complex numbers is "larger" than the set of real numbers, since the set of real numbers is a proper subset of it.
The complement of a set refers to everything that is NOT in the set. A "universe" (a set from which elements may be taken) must always be specified (perhaps implicitly). For example, if your "universe" is the real numbers, and the set you are considering is 0
The set of natural numbers less than four is {1, 2, 3}.
The number -15 belongs to several subsets of numbers, including the set of integers (ℤ), the set of rational numbers (ℚ), and the set of real numbers (ℝ). It is specifically classified as a negative integer, as it is less than zero.

the set of whole numbers less than 0
Real numbers are all numbers. So the answer would be -4 and every number after that in the negative direction. So any number that is less than -4. So, -5, -6, and so on.
Thin of the number line with a solid dot on the number -4. Everything to the left of your dot satisfies real numbers less than or equal to 4. The set it infinite, of course. In set builder notation, {x: x< or = 4}
The set of all real numbers less than or equal to -6 can be represented as (-∞, -6]. This notation indicates that the set includes all real numbers from negative infinity up to and including -6. In interval notation, the square bracket [ denotes that -6 is included in the set, while the parentheses ( indicate that negative infinity is not a specific value in the set.

false
The set of natural numbers less than four is {1, 2, 3}.
Set of even numbers less than 50 and more than 40 = {42,44,46,48}
The LCM of two numbers will never be less than the GCF.
The answer to this is 2, and 0.
