You have seen rational numbers your entire life, but have referred to them as fractions. The word "rational" contains the word "ratio", which is just a comparison of numbers by division. In our lesson on Friday, we discussed that a fraction is really a division problem with the vinculum (fraction bar) serving as a division symbol.Any number that can be expressed as a fraction is rational, and includes repeating and termination decimals that are both positive and negative. Any number on the number line that can be put into the form of a fraction is rational.
