The ratio of staff members to students at a school camp is 3:20. If there are 12 staff
members, how many students are there?

80

Step-by-step explanation:

3 is for the staff members

20 is for the students

if there are 12 staff members

3/20=12/x ,then we multiply the numerator of the first fraction with the denominator of the second and vice versa.

3*x=20*12

3x=240

x=240/3

x=80, so there are 80 students and 12 staff members :)

what?
