Rearrange Equation: Simplifying X = y / (a/b) with Help from Mick

[PonderingMick]

Help,

How do I get X

a/b = y/x

I get to:

x = y / (a/b)

but this seems silly?

Cheers,

Mick

Only that it is a little easier to write it as x= ay/b. Remember that to divide by a fraction, you "invert and multiply": y/(a/b)= y(b/a)= by/a.
