If you're confused, start with real numbers. dividing a number by (1/2) say, is the same as multiplying it by two, so dividing a number by (c/d) is the same as multiplying it by (d/c). Just do a few examples with real numbers first.

you need to have brackets or the equation you have written is ambiguous.
