In the survey, 9 said they prefer the coffee shop next door out of 45 people total surveyed. This forms the fraction 9/45 = 1/5 which converts to 0.2 when you use a calculator or long division. In other words, 1/5 = 0.2
You'll then multiply the result of 0.2 by the total number of employees (250) to get...
0.2*250 = 50
So based on the results of the survey, we expect about 50 employees to say they prefer the coffee shop next door.
Answer: Choice B) 50
