Is 5 a rational number or an irrational number?
Justify your answer/state why?
It is a Rational number because Rational numbers can be written as simple fractions. e.g. 5, -2, 9, 1/2.
However, Irrational numbers are numbers that cannot be written as a fraction and whose decimal numbers go on forever without repeating.
e.g. √2 =1.4142135624, √7, 𝛑
True or False:
All integers are irrational numbers.
False
