Answer:
9 and 3/435
Step-by-step explanation: you need to divide 870 by 96. For that you would get 9. Now multiply 96 by 9. You would get 864. Now subtract 870 by 864. Now you have 9 6/870. Simply that and you would get 9 3/435.
So you start off by seeing how many times 10 can go into 38, it would be 3 times and then your left with 8/10 and if you divide those by 2 you should get 4/5. so your final answer would be 3 4/5
