[Math4u] Simple percentage problem

I'm absolutely stumped on this. In my mind it is very simple but I
can't get it.

An internet service provider has 1335.31 megabits available. A single
DSL subscriber requires 1.46 megabits. A single Cable subscriber
requires 4.16 megabits. There are 3.7 times as many Cable subscribers
than DSL subscribers. How many Cable/DSL subscribers are there?

Help appreciated
