Verified Answer :

Simple....

you have:

\(\frac{a}{b} =c\)

You're trying to find b..so isolate it...

\(b* \frac{a}{b} =c*b\)

leaving you

a=c*b

still not done....

\(\frac{a}{c} = \frac{c*b}{c}\)

\(\frac{a}{c} =b\)

Thus, your answer.

\(\frac{A}{b}\) = c   Multiply both sides by b
A = bc   Divide both sides by c
\(\frac{A}{c}\) = b   Switch the sides to make it easier to read
b = \(\frac{A}{c}\)
