Answer:
The ratio is 3 : 1.
Explanation:
Given that:
Number of attendees in the show = 416
Number of people under 35 = 312
Number of people 35 and older = 416 - 312 = 104
Ratio of attendees under 35 to attendees 35 and older
Attendees under 35 : Attendees 35 and older
312 : 104
3 : 1
Hence,
The ratio is 3 : 1.
