The numbers in the set {x|x= a/b, where a, b are integers and b ≠ 0} are called numbers. List the numbers in the set below that are (a) Natural numbers, (b) Integers, (c) Rational Numbers, (d) Irrational numbers, (e) Real numbers

B = {-7, 1/4 , - 1.6666..., π, 4, 7}

Given that U = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}, A = {1, 3, 4, 5, 9}, B = {2, 4, 6, 7, 8} and
C = {1, 3, 4, 6)

Find the sets:
A U B
A ∩ C
(A U B) ∩ C
(A ∩ B)’
A’
A’ U B’

Use set notation to describe the Venn diagrams below

The universal set U is defined as follows:

U = {x:x∈N,2
The sets M and R are subsets of U such that

M = {odd numbers}
R = {square numbers}

List the numbers of the subset M.
List the number of the subset R.
Draw a Venn diagram that represents the relationship among the defined subset of U.
