Question

Three fourths of the students in class said they like word problems . If fewer than 30 students said they like word problems , how many students are there ?

Answer 1

x < 40. 

Since there are less than 30 students that say they like that and that represents 3/4, you can start by trying to solve the equation. 

3/4x < 30

Where x is the total number of students in the class.
