243=\frac{81}{2}m
Multiply \frac{1}{2} and 81 to get \frac{81}{2}.
\frac{81}{2}m=243
Swap sides so that all variable terms are on the left hand side.
m=243\times \frac{2}{81}
Multiply both sides by \frac{2}{81}, the reciprocal of \frac{81}{2}.
m=\frac{243\times 2}{81}
Express 243\times \frac{2}{81} as a single fraction.
m=\frac{486}{81}
Multiply 243 and 2 to get 486.
m=6
Divide 486 by 81 to get 6.
