Use rule of three:

A.


\begin{gathered} (x)/(9)=(100)/(27) \\ \\ x=9\cdot(100)/(27) \\ \\ x=33.33 \end{gathered}

Then, 9 is 33.33% of 27

B.


\begin{gathered} (x)/(100)=(6)/(60) \\ \\ x=100\cdot(6)/(60) \\ \\ x=10 \end{gathered}

Then, 6 is the 60% of 10

C.


\begin{gathered} (x)/(50)=(70)/(100) \\ \\ x=50\cdot(70)/(100) \\ \\ x=35 \end{gathered}

Then, 35 is the 50% of 70
