Question

Cristine's middle school has a total of 900 students and 45 teachers. The local high school has 110 teachers and a student-teacher ratio proportional to the middle school's. How many students will Cristine find when she gets to high school? A) 900 B) 1100 C) 2200 D) 2500

Answer 1

I had this answer on a test it is definitely 2200 sorry if I answered to late xD

Answer 2

900/45 = 20

so ratio of middle school students and teachers: 900:45 = 20:1

if high school student-teacher ratio as middle school then

x/110 = 20/1

so x = 110 * 20 = 2200

answer is C) 2200
