The inverse property for multiplication states that for every number a, there exists an inverse b such that a*b=1. However, not all numbers on the 12-hour clock have a multiplicative inverse. For example, 6 does not have an integer multiplicative inverse on the 12-hour clock because there is no whole number that will give a product of 1 when multiplied by 6.
