Asked by Amy

2 neon lights are turned on at the same time. One blinks every 4 seconds and the other every 6 seconds, how many times will they blink at the same time?
Answered by Ms. Sue
If they stay on forever, they'll blink an infinite number of times.
Answered by Amy
I got 6*4=24
Answered by Ms. Sue
No.

How long will the lights be blinking? An hour? A day ????

Answered by Amy
In 60 seconds how many times will they blink at the same time?
Answered by Ms. Sue
Ahh -- now your question makes sense.

The least common multiple of 6 and 4 is 12. They'll blink together every 12 seconds.

How many times will they blink together in 60 seconds?
