Answer:
Step-by-step explanation:
They started with 126 oranges. They took 10 for themselves and split the rest between 4 other families.
A: not correct. What actually happened was the reverse of 10 and 4. See the correct answer. (126 - 4)÷10 is the reverse of what actually happened.
B: this is the correct answer. (126 - 10)÷4 = n.
C: Incorrect because 10 oranges were subtracted from the total. They were not added.
D: See the comment for B. In addition, nothing is added to the 126
