These measures are divided correctly so that they equal four beats per measure.

These are in 2/4 time. They have two beats per measure. Remember that an eighth not equals one half of a beat, a quarter not equals one beat, a half note equals two beats, and a whole note equals four beats. To make these measures in 4/4 (four beats per measure) you would have to add four eight notes, two quarter notes, or one half note to each measure.

Ithink that c would make the most amount of sense.

Ilike the chat because if someone has missed anything off their answer they can put it in the chat
