If a third of a dollar is 33.33 cents, what is a third of dollar and a half? If you find yourself adding 33.33 cents to 16.66 cents before you realize that obviously a third of $1.50 is $ 0.50, you have a serious case of “calculatoritis.” Fortunately, the cure is a healthy dose of ratios and proportions.

The technical term for ratios is “rational numbers,” literally numbers that are ratios. The ability to work with rational numbers is a powerful tool for evaluating options, calculating results and representing values. This article is an introduction of some basics; a more in depth study will reveal fascinating characteristics and the intimate part they play in math, science and every aspect of technology.
