3/4 of the tickets have been sold, and the world for 120 tickets left. How many tickets were printed?

Question

 3/4 of the tickets have been sold, and there were 420 tickets left. How many tickets were printed? 

Answer 1

In your title, there is "the world" when you probably meant to say "there were".

I recommend proofreading before submitting.

If 3/4 of the tix were sold, the 1/4 were left; therefore ¼(number printed) = 120.

You should be able to solve this!
