For every left-handed person, there are about 4-right handed people. If there are 30 students in a class, predict the number of students who are right-handed.

24 right handed students

Step-by-step explanation:

1. Out of every 5 students, 4 are right handed and 1 is left handed. We can say that 1/5 of the class is left handed.

2. Multiply 30 by 1/5 to get 6 left handed students in the class.

3. Take the 30 students in the class and subtract the 6 left handed students.

4. The remaining 24 students must be right handed.
