Question 185882
I assume you meant to type A = (1/9)(s).

We can write (1/9)(s) as s/9.  Both expressions mean the same thing.  To get s/9, I simply multiplied the numerator 1 by s.

We now have the equation: A = s/9

Multiply both sides by 9.

9A = s

=================================

THE PROVE:

A = (1/9)(9A)

A = A...It checks!

The answer for s is 9A.
