1) listing method: { 1,2,3}
rule method: {x| x is a positive whole number less than four}
2) listing method: { 2,4,6,8,....}.
rule method: {x| x is a positive even number }
A 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
A number cannot have a subset, only a set can.The set containing 6.45 is {6.45} and it has two subsets: itself and the null set = {}.
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.
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.
Not at all. Every whole number is rational.
