its opening day at an amusement part. there are 132 people in line before it officially opens. if the ratio of adults to kids waiting to get in is 5 : 6, how many kids are waiting in line?
A 12
B 60
C 66
D 72
To find the number of kids waiting in line, we need to determine the ratio of adults to kids in the line.
The total ratio is 5 + 6 = 11 parts.
Since there are 132 people in line and the total ratio is 11 parts, each part represents 132 / 11 = 12 people.
Therefore, the number of kids waiting in line is 6 parts * 12 people/part = 72 kids.
The correct answer is D) 72.
