Can someone transpose the following formula for me so that I can find b when I know the values of a and c - thanks
(a-b) x 100 = c ___
another way of presenting that would be [(a/b)-1] x 100 (I think)

p.s. If anyone's interested we're trying to work out the moisture content when we know the original weight and the percentage mc :)
b = a / ( 1 + c/100 )
or
b = 100 x a / (c + 100)

Start by multiplying both sides by b, which gives:
(a-b) x 100 = bc
100a - 100b = bc 100a = bc + 100b 100a = b(c + 100) and finally 100a b = _______ c + 100HTH
Thank you both. I am, as usual, astounding that anyone can get their heads around such things
Many thanks

Glad to help.
Just simple algebra really, well before GCE level (when I were nobbut a lad). OTOH, I never could remember all the functions for integral calculus. Fortunately, DIY, PCs and work don't need that stuff, mainly geometry and the occasional trig function.

That's a very cavalier attitude to take....

Well, I guess one has to do something while waiting for the Aga to warm up again to cook after it has been turned off for overheating the house :o). OTOH I share your astoundment!
