To me, it seems easier to read them, so I guess that makes it correct, but I was wondering if there was another way to place the following durations into easier meters:

21/16
8th, 32nd, 32nd, 32nd, Dotted 8th, 8th triplet, 8th, 32nd, 32nd, 32nd, Dotted 8th, 8th triplet.

35/32
8th, 32nd, 32nd, 32nd, Dotted 8th, 8th triplet, 7 16th notes.

Let's group these into eighth notes:
1)
2 Dotted 8th= 3 8th = 6 16th notes
6 32nd = 1.5 8th = 3 16th ntoes
2 eighth triplet = 4 8th = 8 16th notes
2 Eighth notes = 2 8th = 4 16th netes

21/16. That is the simplest way.

2)
1 8th = 2 16th = 4 32nd
3 32nd = 1.5 16th = 3 32nd
1 Dotted 8th = 3 16th = 6 32nd
1 8th Triplet = 4 16th = 8 32nd
7 16th = 7 16th = 14 32nd

35/32. Again, you're right :]

These are the simplest ways

you're making the first one way too complicated. Its either 2 measures of 3/4 or 1 measure of 6/4.

and the second one would probably be written in alternating 3/4 and 7/16

How do you get that?
Cause 16 and 21 don't share a 2 or a 3 to be divisible by to make it that.

my bad, i didn't read that correctly. for some reason i was treating the 32nds as 16ths

anyway...

mind if i ask what the heck youre writing in that meter?
