Benny was told to practice playing piano for 4/11 of an hour per day. benny has already played 3/14 of an hour today. how many hours does benny still need to practice today? what are the given facts? what is asked in the problem? what is the hidden question? what are the operations to be used? what is the nuber sentence? what is the answer to the problem? ( answer fast. if you answer, you very much! )

Solution:

4/11 = 0.36

3/14 = 0.21

He still needs to play 0.15 of an hour or 3/20 of an hour.

Given facts - Amount he has to play, and the amount he played.
Question - For how long does he need to practice to meet the required time.
Hidden question - There is nothing hidden
Operations used -  divisions (not necessary), subtractions and conversion (only if used division).
