One hundred students are assigned lockers 1 through 100. The student assigned to locker 1 opens all 100 lockers. The 2nd student closes all lockers whose numbers are multiples of 2. the student asssigned to locker 2 changed the status (e. g. the locker number 3 which is opened gets closed, locker 6 gets opened). The student assigned to locker number 4 changed the status of all lockers whose numbers are multiples of 4. And so on for all 100 lockers.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
