In the School Orchestra, 3/5 of the students play the trumpet. Of these students, 1/6 also play the trombone. What fraction of the members of the

1/6 of 3/5  play both.....so

1/6  * 3/5    =  

3/30  =

1/10   play both

Let S be number of students in the Orchestra, then we have:

3/5S- students who play the trumpet, but we have:

1/6 of 3/5S play the trombone as well, 0r:

1/6 X 3/5S=1/10 of students who play both the trumpet and trombone.
