Documentation:

Division for physical-quantities. The '/' operator for complex numbers (part of KIF specification) is overloaded to operate on physical quantities. Defined in terms of multiplication and real exponentiation operators.

and also:

If $tau_1$, ..., $tau_n$ are numbers, then the term {tt (/ $tau_1 ... tau_n$)} denotes the result $tau$ obtained by
dividing the number denoted by $tau_1$ by the numbers denoted by $tau_2$ through $tau_n$. An exception occurs when $n=1$, in which case the term denotes the reciprocal $tau$ of the number denoted by $tau_1$.
