Question

17. in your class, 4/5 of the students are right handed. If there are 20 right-handed students, what is the total number of students in the class?​

Answer 1

25 students

Explanation:

Variable x = total number of students

4/5 × 20/x

Cross multiply

4 × x = 5 × 20

4x = 100

Divide 4 by both sides

x = 100 ÷ 4

x = 25 students total
