The ratio of adult to total for the information given would be:
6 (adult)
10 (total)
We can now create a pair of equivalent ratios to determine the number of adult tickets for 120 total tickets:
6 adult = x
10 total 120 total
We can multiply the numerator and denominator by 12 to determine the number of adults out of the 120 total:
6 adult • 12 = x
10 total • 12 120 total
x = 72 adult tickets
The number of student tickets would be 120 - 72 = 48 student tickets
