Answer:

D. 300/3 = 100

Step-by-step explanation:

He needs to divide the number by 3 since he is placing 3 erasers in each bag. He needs to divide 280 by 3. 280 divided by 3 is not a choice. The closest choice is 300/3, so that is the correct answer.
If you use compatible numbers the answer would be 300÷3=100
