The school marching band is made up of middle and high school students, but it still 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 has increased to 2:7. If there are 18 middle school students in the group this year, how many fewer high school students are there in the group this year compared to last year? EXPAIN. This year:
middle:top=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:top=1:8=y:8y
but y + 8y = 81
y = 9
So last year we had 9 college students and 72 high school students
So difference at top = 72-63 or 9 less high school students I really think it’s 72-63 or 9 I think 9 is just 23 college help please No it’s 12 because you convert the 720 to get 120 then get 16-4 =12 okay? I did this problem in math class (I’m a kid by the way) Thanks for the help guys the answer is 9 No it’s 12 because you convert the 720 to get 120 then get 16-4=12 Luke is right Luke is right Yes his answer is valid I agree with everyone else Luke is right The student to faculty ratio in a small college is 17:3. The total number of students and faculty is 740. How many faculty are there in the college? How many students? 12 my teacher told me it’s not 9 and it was 12 please help Jeanette wants to save money, ratio of money in Jeanettes savings account to amount of amount of money in her checking account was 1:6 her checking account is 4:3 if Jeanette had $936 in her checking account before she transferred money, how much money does Jeanette have in each account after transferring money 23 333 333 333 333 333 333 333 333 333 333 to 1.
