Question

e) Two TV movies starts at 8 p. m. One channel airs commercial breaks every 12 minutes and the other channel airs the commercial breaks every 15 minutes. At what time will both the channels start commerc breaks at the same time?​

Answer 1

We need to find the least common multiple (LCM) of 12 and 15 to determine when both channels will start commercial breaks at the same time.

The multiples of 12 are: 12, 24, 36, 48, 60, ...

The multiples of 15 are: 15, 30, 45, 60, ...

So, the LCM of 12 and 15 is 60.

This means that both channels will start commercial breaks at the same time after 60 minutes.

The movies started at 8 p.m., so both channels will start commercial breaks at 9 p.m.
