    algebraic equation help

    I'm told that (R = v/f*L) is the same thing as (L = v/f*r) but I can't seem to get there algebraiclaly. If anyone can show me all the steps I'd be very appreciative.

    Use brackets where they're needed please. Is it \displaystyle \begin{align*} R = \frac{v}{f\cdot L} \end{align*} or \displaystyle \begin{align*} R = \frac{v}{f}\cdot L \end{align*}? What you wrote implies the latter...

    \displaystyle \begin{align*} R &= \frac{v}{f \cdot L} \\ R \cdot f \cdot L &= v \\ L &= \frac{v}{R \cdot f} \end{align*}
