Question

A random survey found that 6 of the 20 people surveyed prefer listening to rock music. Based on those results, about how many

people prefer listening to rock music from a population of 100 people?
A. 18
B. 24
C. 48
D. 30​

Answer 1

D. 30

Explanation:

6/20 = x/100

600 = 20x

600/20 = x

x = 30

Answer 2

30%

Convert fraction (ratio) 6 / 20 Answer: 30%

Explanation:

The strategy here is to see how many times the "percent number" (in this case, 25) goes into 100, and then count by that number until we reach 100-the whole thing.
