**Question:** Identify which type of number the following examples belong to:

(Hint: some can belong to more than one)

a)5

b)π

c)√11

d)8/3

a) 5 is a whole number, so it is an integer. Furthermore, all integers are also rational numbers and real numbers, so 5 falls into these categories as well. Lastly, 5 is only divisible by 1 and itself, so 5 is also a prime.

b) Real and irrational

c) \sqrt{11} is not a whole number, and it cannot be written as a fraction, so it is irrational. Also, like all numbers on the number line, it is a real number.

d) 8/3 is a fraction, so it is a rational number. Like all rational numbers, it is also a real number.
