Compound to simple time signatures

on: February 10, 2015, 04:35:00 PM

Hello, I've come across this question and I'm a little puzzled about the last bar. The question was to change the time from compound to simple time without changing the rhythm. I'm a bit stumped as to why the minims haven't changed to crochets and why the crotchets didn't change to minims!!

Any words of wisdom on this would be greatly appreciated!!

To convert a/b time to c/d time you take each note (x) and the new note (y) is :

y = (c/a) * (b/d) * x

So in this case

y = 3/9 * 4/2 x
= 1/3 * 2 * x
= 2/3x

So, a dotted mimim changes to a minim.
