Answer from: starreee

they will blink 4 times at the same time in one minute

Step-by-step explanation:

you have to find the least common multiple of 5 and 3

LCM of 5,3 = 15

So, the two lights will blink together every 15 seconds.

No.of times blinking together in one minute = 60/15 = 4

Answer from: Zgt

To answer this question, we need to determine how many common multiples there are between 3 and 5, that are lower than 60.

It turns out that every common multiples of 3 and 5 is also a multiple of 15. So, there are (60/15) = 4 such common multiples.
So the answer is 4.
