Answer 2

A rational number is any number that can be expressed as a fraction of two integers. Here are some examples of rational numbers

5 is a rational number because it can be expressed as a fraction 5/1

1.75 is a rational number because it can be expressed as a fraction 7/4

\[\sqrt{2}\] is NOT a rational number because you can NOT express it as a fraction it equals 1.414213562

Now try using your numbers and see which ones you can express as a fraction
