Art class / all classes = 16 / (26 + 19 + 21 + 16 + 32) = 16/114 = 8/57
LCM is found by finding the factors of both and making sure that both are inthere
9=3 times 3
12=2 times 2 times 3
common one is 3

2 times 2 times 3 tiimes 3=36
answer is 36
Answer:
B. 40
Step-by-step explanation:

In this sense the sample size is 50 million because that's the one we are investigating.
Similarly our concern of interest for investigation is 40, so that's the sample size.
