Need this Maths prob Solved please

[Rockabilly]

This is driving me bonkers !!!
Can anyone transpose how to find "F" ?
..........B X C
A = -----------
.......D X E X F

........D X E X F X A
C = -------------------
................B

..............B X C
E = --------------
............D X A X F

...........D X E X F X A
B = ------------------
...................C

Cheers !

There you go mate, ive made all the "F"s in RED and BOLD so you can find them too

Thanks Mike, I can see it better in red ;-)
An accountant friend of mine worked it out for me >
........B x C
F = ..---------
......D x E x A

'F' is the imaginary gear ratios in an auto gearbox that you can't count teeth of.
I have speeds vs revs via true gps & revs & the Mitsu quoted gears are bulltish.
Now I know the Real imaginary gear ratios by the transposed formula with my speeds.
It would be handy for figuring out what gears were put in a custom man box.

I was just about to give you that exact answer

Mate, you just confused me enough for the rest of the year :huh: :unsure: :wacko:

Have a drink Mike ;-) I posted a mph & rpm etc thread for when ya fist as a part..
Auto gearing is just clutches, a barrel & planetry gears & I'm glad I didn't design it.
I can change it's final drive & build it tuff, but they are confusing.
How the F do I add Solved to the topic ? I'm f'n confused ;-)
Cheers !

That was easy and took me a bit over a minute to figure out once I printed it out.
All you need to do is look at the constant in your equations.
Pull out the equations marked "A =", and the one marked "E =".
The top number remains constant as "BXC"
The bottom denominator changes between the letters E D A and F.
So it was a simple case of just replacing the "?=" with one of the letters in the bottom... in our case "F".
Too easy

Oh and another answer is "1".
If all letters are given the numerical value of "1"...... then the answer is also "1" lol

Actualy I used 3rd which is 1:1 to test the reverse formula & came up with 1 lol

took me until that was written to understand the formatting

F = BC / ADE

they were all the same equation, just with different subjects...
