Yesterday, I was filling up some premium gas at a premium price, and began wondering why the heck they add the 9/10ths to the end of it? If the oil companies need that extra penny, just take it! Why do they need to bring fractions into my happy fraction-free lifestyle? Considering that they add a buck (or more) per gallon to the price of gas every summer anyway, I just don’t see the need for the extra 9/10ths of a cent. Is this something that was a really great idea in the 1920′s when a penny was a big deal? Or maybe it’s a conspiracy designed by high school math teachers to make us think that fractions are used “in the real world”. Of course I don’t want to pay more than I already do for gasoline, but that fraction really cramps my style when I’m pumping my fuel. Did I miss the day in school when they explained why this insanity exists? Is it common knowledge? Somebody help!
