Answer:
600 seats
Step-by-step explanation:
We know there is 120 seats on a balcony and that is
of the total seats, we want to find the total number of seats so,
120 seats = 
We know that a whole fraction sums to 1 so for example 
120 seats = 
Multiply both sides to make it a whole fraction
600 seats = 
So if there is 120 seats and that number is only
of the total number of seats then the total number of seats is 600
