Answer:
H
Step-by-step explanation:
To find purple, you divide 162 by 3 as there are 3 people who like red for every one person who like purple. To find blue, you need to divide 162 by 3, which is 54, and then multiply it by 9 because there were 9 people who like blue for every person that liked purple.
If you mean to the nearest HUNDREDTH the answer is 14.60.
Let, the number = x
It would be: x * 0.135 = 57
x = 57 / 0.135
x = 422.23
