Question

The ratio of the number of adults to the number of students on a field trip has to be 2:11. Last year there was 504 more students on a field trip. If the school is expecting the same attendance this year, how many adults have to attend the field trip?

Answer 1

Answer:

112 adults

Step-by-step explanation:

2x+504=11x

11x-2x=504

9x=504

x=56

The ratio is 2:11 so we multiply 56 by 2 and 11. The 2 represents the Adults and the 11 represents the students.

56*2=112 adults

56*11 = 616 students

Just to double check if you do 616-112 it is exactly 504, Therefore the amount of adults is 112.

Have a great day!
