Question

Christine's middle school has a total of 900 students and 45 teachers . The local high school has 110 teachers & a student-teacher ration proportional the middle school . How many students will Cristins find when she gets to high school ?

Answer 1

Answer:

2,200 students

Step-by-step explanation:

To find the number of students, create a proportion which is two equal ratios. Since the middle school and the high school are proportional then they have equal ratios.

$\frac{students}{teachers}= \frac{900}{45}=\frac{x}{110}$

Solve for x by cross multiplying by multiplying the numerator and denominator of each fraction.

900(110) = 45(x)

99,000=45x

2,200 = x
