Wow Thanks for that, I can understand that easy enough. The thing I would be unsure of is what e gearing represents. So the bigger the number the higher the gearing? So in reality when it comes up as 1.24 and 1.30?sorry if that's a stupid question but it's how you learn. The whole point of thinking of it is to give me lower gears up the big 25%plus hills around these parts. I want to be able to have gearing I can spin more and keep up higher cadence. However I also don't want to lose the top end. I basically want my cake and eat all of it

The higher the number, the higher the gear

So if you had a 39 ring and 39 sprocket, the "answer" would be 1. If you took it to the extreme and fitted an MTB triple drivetrain, then you might have a 24 ring and 36 sprocket, which would give 0.67.

At the high end, an "answer" of slightly more than 4 is more or less normal. 52/13 gives exactly 4, 50/12 =4.17 so a slightly higher gear. 48/11 = 4.36, so even higher

Hope that helps!

I should say too that there are lots of gear inch tables about, should be easy enough to find one on the internet. The only thing they do is convert the "answer" from above to the number of inches you move forward along the road for a single turn of the pedals, in any given gear. That depends on wheel and tyre size, which is useful if you want to compare for example a road bikea and MTB, or an MTB 26er and 29er. For comparing gears on the same bike with the samewheels, gear inches aaren't needed.
