In Mrs. Marshall's classroom, 6/7 of the students play sports. Of the students who play sports, 4/5 also play an instrument. If there are 35 students in her class,how many sports and an instrument?
if 6/7 play sports, then 30 out of 35 play sports. if 4/5 of those who play sports play an instrument, then 24 out of 30 play an instrument. Which means 24 play an instrument and a sport.
