    You know that 500mg is related to 500mL; that is,\[500mg \iff 500mL\]But that's the same as (after dividing both sides by 500),\[1mg \iff 1mL\]but again, that's the same as\[\frac{1mg}{h} \iff \frac{1mL}{h}\]which again is the same as\[\frac{80mg}{h}\iff \frac{80mL}{h}\]

    They're a set of equivalent statements.

    You could write it out word-for-word if you want to.
