If you want to solve
(a)/(b) = c for
b, start by getting rid of the fraction.

Multiply both sides of the equation by
b.


b\cdot (a)/(b) = b\cdot c

This will get rid of the fraction on the left and give you


a = b\cdot c

Now this is a regular old equation without fractions. To get
b by itself, you need to divide away
c from both sides of the equation.

Can you finish it from there?
