18 of the students in history class past a history test if the students are 75% of all the students in the class how many students are there in history class

24 people in the history class.

Step-by-step explanation:

Let the total number of people in the class = x. I do this rather a long way because people often have trouble dealing with the division of fractions.

Equation

75/100 * x = 18              Multiply by 100

Solution

75x = 18*100

75x = 1800                     Divide by 75

x = 1800/75

x  = 24

There are 24 people in the class
