Example Question #21 : Grade 8
Which of the following answer choices displays an irrational number?
Our answer choices consist of two types of numbers: rational numbers and irrational numbers. In order to correctly answer this question, we need to know the difference between the two types of numbers.
Rational numbers are numbers that we use most often, and can be written as a simple fraction.
Irrational numbers cannot be written as fractions, and are numbers that have decimal places that never repeat or end.
In this case, is our only irrational number because it cannot be written as a simple fraction.
