Question

Ronald states that the number 1/11 is not rational because, when converted into a decimal, it does not terminate. Nathaniel says it is rational because it is a fraction. Which boy is correct? Explain.

Answer 1

A rational number is any number that can be written as a fraction with
whole numbers on top and bottom.  ' 1/11 ' fits that description nicely.

It also turns out that ANY number that can be completely written down
on paper, using digits, a fraction bar, and a decimal point, is rational. 
' 1/11 ' also meets that requirement.
