this year:
middle : high = 2 : 7 = 2x : 7x
2x = 18
x = 9
so this year we have 18 high and 63 middle
for a total of 81 students
last year:
middle : high = 1:8 = y : 8y
but y + 8y = 81
y = 9
So last year we had 9 middle and 72 high school students
So difference in high = 72-63 or 9 high school students fewer
The school band is comprised of middle school students and high school students, but it always has the same maximum capacity. Last year the ratio of the number of middle school students to the number of high school students was 1:8. However, this year the ratio of the number of middle school students to the number of high school students changed to 2:7. If there are 18 middle school students in the band this year, how many fewer high school students are in the band this year compared to last year? Expain.

The student to faculty ratio at a small college is 17:3. The total of students and faculty is 740. How many faculty members are there at the college? How many students?
i think 9 is right
No it's 12 because you convert the 720 to get 120 then get 16-4=12 ok? I done this problem in math class (I am a kid by the way)
