# How do you solve the proportion 17/5.2=f/13?

May 17, 2015

to solve for $f$ in the equation $\frac{17}{5.2} = \frac{f}{13}$

we would multiply both sides by $13$

$13 \left(\frac{17}{5.2}\right) = 13 \left(\frac{f}{13}\right)$

as $f$ is dived by $13$ and now we multiply by $13$ we will be left with $f$.

so we have

$13 \left(\frac{17}{5.2}\right) = f$

Therefore $f = 42.5$

thus you can rewrite the above proportion as:

$\frac{17}{5.2} = \frac{42.5}{13}$
