Answer:
30 students in the class eat lunch every day
Step-by-step explanation:
- The total number of students in the class = 36
- The fraction of students who bring lunch is 1/3
In absolute numbers this works out to 36 * 1/3 = 12 students who bring lunch
- The fraction of students who order lunch = 1/2
In absolute numbers this equals 36 * 1/2 = 18 students who order lunch
- Assuming those who bring lunch and those who order lunch actually eat lunch the total number o students eating lunch every day
= 12 + 18 = 30 students
Answer
30 students in the class eat lunch every day
(There are 6 students who neither bring lunch nor order lunch. Presumably they have decided to skip lunch every day :)
