Help me find time signatures for these
three please?

The first one is probably 3 over 4, second one is 4 over 4, and the third one i think is 2 over 4, im not too sure :'>

Explanation:

A would be 3/4

B would be 4/4

C would be 4/4

Explanation:

If you look at the 2nd measure in bar A, you can se the 8th note which is one beat, the quarter note which is one beat, then one beat of rest, so in total it would be 3/4 for the time signature.

For B, the half notes are worth 2 beats, so add 2+2=4 so the time signature would be 4/4

For C, there are 4 sets of 16th notes, so that would be 4/4

Hope this helps!!
