Answer:
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
