    Let the number of pages Lynn can type be x, then the proportion of the number of pages and the time it takes is given by \dfrac{1\text{ page}}{p\text{ minutes}}=\dfrac{x\text{ pages}}{5\text{ minutes}}.

    Multiplying both sides by the LCD, 5p, we have 5p\times\dfrac{1\text{ page}}{p\text{ minutes}}=5p\times\dfrac{x\text{ pages}}{5\text{ minutes}}.

    \Rightarrow5=xp.

    Then dividing both sides by p gives x=\dfrac{5}{p}.

    Therefore, the number of pages she can type in 5 minutes is \dfrac{5}{p} pages.
