I also am a heavy user of the cross-multiply and divide technique, which is a way I tend to represent "this is to this as that is to that" mathematically. So, you could cross-multiply 4.8 and 100 to get 480. Then divide that by 7 which equals the same thing I told you earlier. Sort of a 4.8 is to 7 as X is to 100 set up.

I think I made that more complicated than it needed to be.
