When I own a nationwide chain of gas stations, my prices will end in 7/10ths of a cent. You may wonder why I don't just make it 8/10ths of a cent. Well, if I did that, there would be people who were upset that I didn't reduce it to 4/5ths, and if it were 4/5ths, there are people who would wonder, "Now, is that more or less than 9/10ths?".

It's best go with a nice safe fraction like 7/10ths.
