Are all rational numbers in the set of whole numbers?
No. But all whole numbers are in the set of rational numbers. Natural numbers (ℕ) are a subset of Integers (ℤ), which are a subset of Rational numbers (ℚ), which are a subset of Real numbers (ℝ),which is a subset of the Complex numbers (ℂ).
Is a set of whole numbers a subset of the natural numbers?
Yes, if all of the whole numbers are positive ones.
Which subset of rational numbers best describes the number of coins in a jar?
Which subset of the rational numbers best describes the dimensions of a rectangle
Is the set of all integers the subset of the set of whole numbers?
Integers and whole numbers are the same thing. The sets are identical.
Does every point on the real number line correspond to a rational number?
No. There are several real numbers that are not rational (e.g. pi). However, every rational number is also a real number. In general, whole numbers/natural numbers is a subset of the integers (i.e. every whole number is an integer), the integers is a subset of the rationals, the rationals are a subset of the real numbers. I think the real numbers are a subset of the complex numbers, but I'm not 100% positive on that.
