The answer is B. 850
2550 ÷ 3 = 850, a here is how I did it. 3 can't go into 2, but it can go into 25 8 times for 24, so put your 8 above the first 5. 5 - 4 = 1 so drop you 1 down along with you 5 for 15. 3 can go into 15 5 times so put your five next to your 8 then solve. 15 - 15 = 0. Add you 0 next to your 5. Then, your answer will be 850.
