I have never seen an equation set up like this before. What do the colons represent? I'm sure it's a very simple equation and I'm stumped.

500 is to x as 200 is to 1
It can be expressed as...
500 in the numerator is to x in the denominator, as 200 in the numerator is to 1 in the denominator...
500 in the numerator is to x in the numerator, as 200 in the denominator as 1 is in the denominator...
Division is equivalent of Fractions, the fraction and division signs are interchangeable, but it is weird to write equations as such.
500:x=200:1 is the same as 500/x=200/1
There are two ways to solve the problem.
You can cross multiply to get 200x=500
The other way is to multiply 200 and 1 both by 2.5 because 2.5*200=500 !
Therefore 2.5*1=2.5 and x=2.5 again.
