Multiply both sides by \(a\).
\[9=\frac{2}{3}a\]
Simplify \(\frac{2}{3}a\) to \(\frac{2a}{3}\).
\[9=\frac{2a}{3}\]
Multiply both sides by \(3\).
\[9\times 3=2a\]
Simplify \(9\times 3\) to \(27\).
\[27=2a\]
Divide both sides by \(2\).
\[\frac{27}{2}=a\]
Switch sides.
\[a=\frac{27}{2}\]
Decimal Form: 13.5
