\frac{\sigma }{5}=M
Swap sides so that all variable terms are on the left hand side.
\frac{1}{5}\sigma =M
The equation is in standard form.
\frac{\frac{1}{5}\sigma }{\frac{1}{5}}=\frac{M}{\frac{1}{5}}
Multiply both sides by 5.
\sigma =\frac{M}{\frac{1}{5}}
Dividing by \frac{1}{5} undoes the multiplication by \frac{1}{5}.
\sigma =5M
Divide M by \frac{1}{5} by multiplying M by the reciprocal of \frac{1}{5}.
