Addison plays 1/2 of a song in 1/4 of a minute. How minutes will she need to play a full song?
STALIN [3.7K]

Answer:

30 minutes

Step-by-step explanation:

She plays 1/2 of a song in 1/4 of a minute so that would be 15 minutes because if you divide 60 by 4 you would get 15. You would multiply 15 by 2 because if she plays a full song you multiply 1/2 by 2 to get a whole. So she will need 30 minutes to play a full song
