Question

In a certain school, 20% of students are below 8 years of age. The number of students above 8 years of age is 2/3 of the number of students of 8 years of age which is 48. What is the total number of students in the school?

Answer 1

Morgan, the word "of" means to multiply.

 

(2/3)(48) = 96/3 = 32

 

There are 48 + 32 = 80 students 8 or older, and they are 80% of the total (100% - 20%).

 

.8t = 80

t = 100

 

There are 100 students total.
