Jack is learning to play the piano he knows that a piano has 88 keys and that there are 12 unique keys in each group called an octave how many complete octaves are on a pianoshow work math

All you would have to do for this is divide 12 by 88. So, 88/12 is 7.333333. That isn't a full number, which is probably what is confusing you. Although, since the question is asking for how many COMPLETE octaves on a piano, it would be 7 because there are 7 complete octaves, and a little more.
