find the least common multiple of 25 and 30, which is 150

so they will flash at the same time every 150 seconds which equals 2.5 minutes

How to divided the two numbers

Elina [12.6K]

Answer: 30

Step-by-step explanation:

5 in fraction form is 5/1. You can't divide fractions so you keep the 5/1 the same, turn the divide sign into a multiplication sign, then flip the 1/6 to 6/1 then multiply across. The answer would be 30/1 or 30.
