Answer:
56 students are in band
Step-by-step explanation:
Since 75% is basically 3/4, you should find first how much people are in 1/4 or 25%.
You can do this by dividing 42 and 3
42 divided by 3 = 14
You can check your answer because there are 42 students who play wind instruments and 14 + 14 + 14 = 42
Then you add another 14 to 42 since the students who play wind instruments are only 75%
42 + 14 = 56
56 students are in band
