Question

A/b = c for b help me please this alot of a points please

Answer 1

$\frac{A}{b}$ = 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 = $\frac{A}{c}$ 

Answer 2

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.
