The use of the decimal system (base 10) is really more or less arbitrary. It may be related to the fact that most humans have 10 fingers, and used them for counting at some moment. But mathematically, the number 10 has no merit over other numbers; any base (like 6, 12, or 17) would work as well. In fact, the number base 6, or a multiple like 12, would make it somewhat easier to work with fractions - being based on the smallest two prime numbers.
