3/4 because when you add it all up and then add 1 2/4 two time and then subtract it you will get 3/4.
Answer:
3/4
Step-by-step explanation:
When you divide 287 by 68, when it is not rounded, you will get 4.22058823529... (repeated decimal), but when you round it, you can either get the following: 4.22, 4.2, or 4 (choose which ever you want to pick out of these rounded forms.)
Hope this helped!
