Answer: 20:15:12
Step-by-step explanation:
First, find the LCM of the numbers 3 4 5 which is 60
Then divide 60 by 3 4 and 5
We get 20 15 and 12 in order so that's the ratio
20:15:12
you add the amount of people in each section that fits into the category. So, 11 people from 6-6:29 and 15 people from 6:30-6:59 and then 8 people from 7:30-7:59 so you get 34 people total
