There are 250 students taking either band or chorus. if there are 180 students taking band and 60 students in both mad and chorus, how many students are only in chorus

250-180= 70  because 180 are in band and there are a total of 250 students
70-60= 10 because there were 70 students were left and 60 students were in both and the question wants to know how many students are in chorus ONLY.

and so the answer is 10.

hope it is right, sorry if it is not :)

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
