Step 1. Rational numbers are that can be expressed as fractions and as a ratio of whole integers like:
,, , and =0.3333333... and so on. The last example has repeating digits so it is a rational number.
Step 2. Irrational numbers cannot be expressed as fractions and as a ratio of whole integers like:
, , . Note that pi or pi=3.1415926... has non-repeating digits and therefore is an irrational number.
I hope the above steps and explanation were helpful.
