∙ 11y agoA set can have a subset, a number cannot - whether or not it is negative.
A whole number is not a set of any kind and so cannot be a subset of rational numbers.
The subset consisting of the one number, 7.5 : {7.5}
yes
The "subset."
A number does not have a subset.
A set can have a subset, a number cannot - whether or not it is negative.
No, rational numbers are not a subset of integers.
proper subset {1,2} improper subset {N}
pi is a single number , not a set. Since it is not a set, it cannot have a subset.
A whole number is not a set of any kind and so cannot be a subset of rational numbers.
Yes, but not a proper subset: they are the same set.
The subset consisting of the one number, 7.5 : {7.5}
yes
No. There is one even prime.
Not at all. Every whole number is rational.
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.
