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 numbersare numbers that we use most often, and can be written as a simple fraction.
我rrational numberscannot be written as fractions, and are numbers that have decimal places that never repeat or end.
我n this case,
