\[60\%\]

\(\frac{9}{15}\) simplifies to \(\frac{3}{5}\). If you don’t quickly know that \(\frac{3}{5}\) is \(60\%\), then maybe you know that \(\frac{1}{5}\) is \(20\%\). Then, multiply by three to get the equivalent for \(\frac{3}{5}\).

Here are some common percentage conversions to memorize:

\[\frac{1}{2} = 50\%\] \[\frac{1}{3} \approx 33\%\] \[\frac{2}{3} \approx 66\%\] \[\frac{1}{4} = 25\%\] \[\frac{3}{4} = 75\%\] \[\frac{1}{5} = 20\%\] \[\frac{2}{5} = 40\%\] \[\frac{3}{5} = 60\%\] \[\frac{4}{5} = 80\%\]
