Two out of 15 people surveyed were left handed. Based on the data how many people would you predict to be left handed out of 405 people?
A.15
B.27
C.810
D.54
Since there are a total of 405 people, you first divide 405 by 15 to get 27. Then multiply 27 by 2 considering two in 15 people are left handed, and you're left with 54 people.
