Step-by-step explanation:
number of times being a crew mate = 5
number of times being the imposter = 2
The ratio of crewmate to imposter = 5:2
Number of times Fanta was a crew mate = 20
let the number of times Fanta would be an imposter = x
Ratio = 20:x
equating both:
5:2 = 20:x
Hence, the number of times fanta was the imposter is 8
