The pendulum of the wall clock makes 198 vibrations in 3.3 minutes how many vibrations

The pendulum of the wall clock makes 198 vibrations in 3.3 minutes how many vibrations to do in 3 minutes 12 seconds.

Let’s solve this task by steps with explanations.
1) 3 minutes 12 seconds = 3 minutes + 12/60 minutes = 3 minutes + 1/5 minutes = 3.2 minutes;
2) 198: 3.3 = 60 oscillations the pendulum makes in one minute, since in 3.3 minutes it makes 198 oscillations;
3) 60 * 3.2 = 192 oscillations will be made by the pendulum in 3.2 minutes, since it makes 60 oscillations per minute.
Answer: 192 hesitation.
