Answer 1

To find the total number of sixth-grade students at Luehrs Middle School, we can set up a proportion using the information given:

112/total number of sixth-grade students = 35%/100%

Solving for the total number of sixth-grade students, we get:

112/x = 35/100
100(112) = 35x
11200 = 35x
x = 11200/35
x = 320

There are 320 sixth-grade students at Luehrs Middle School.
