In one ivy tech region the number of students in math 136 is 20% more than the number of students in math 123. if there are 480 students in math 136, how many students are in math 123?

Number of students in Math136 = 480

We are given that the number of students in Math136 is 20% more than the number of students in Math123. Let the number of students in Math123 be x. So we can set up the equation as:

Number of students in Math136 = 20% more than number of students in Math123

Number of students in Math136 = 20% more than x

480 = 20% more than x

480 = 20% of x + x

480 = 0.20x + x

480 = 1.20(x)

x = 480/1.20 = 400

This means, there are 400 students in Math123.
