#### Answer

$A=sM$

#### Work Step by Step

$\bf{\text{Solution Outline:}}$
To solve the given equation, $
M=\dfrac{A}{s}
$ for $
A
,$ use the properties of equality to isolate the variable.
$\bf{\text{Solution Details:}}$
Using the properties of equality to isolate the variable, the equation above is equivalent to
\begin{array}{l}\require{cancel}
M=\dfrac{A}{s}
\\\\
s\cdot M=s\cdot \dfrac{A}{s}
\\\\
sM=A
\\\\
A=sM
.\end{array}
