ok somebody be kind here and help me out.

a math equation lets just make it easy for our purpose here

1+1
---------------
2+2

im old and its been along time since i was in school, what the hell does the line between mean? is it a fraction? divide the answer to one problem by the other?

here is a complex one precipitation rate =

96.3xgpm
-------------------
sq ft of area

again all i want to understand is what does the line between the 2 equations signify?

It could be a fraction, a ratio, or a division equation.

But, going off your example, I'm going to say its a division equation.

so lets say 96.3x 10 gpm divided by a square footage of 100 is a precip rate of 9.63

whenever you see one set of numbers over another set with a line in between them, it always means you divide the top number by the bottom number...

it is a fraction, but a fraction is an undivided representation.. you still can do the division..
ie
1/2(one divided by 2)=.5
4/5=.8 etc..

Get a copy of Watkins' Turf Irrigation Manual and you can play with all types of these formulas.
