Question

Two-fifths of the people enrolled in a seminar held master's degrees. If 18 people has master's degrees, how many people enrolled in the course?

Answer 1

This means that 2/5=18 people.

 

You can set up a proportion to solve this

 

2                 18

_      =    _______    

 

5                 x

 

What you are really saying is that 18 people out of an unknown number is 2/5 of that number.  You can cross multiply now to set up an equation where you solve for x.

 

2x= (5) (18)

2x = 90

x=45
