Answer:
Once you reach your final answer, for example lets say it is 9.5482, the third decimal place would be the '8'. From here, you must look one decimal past, so the fourth decimal, in this case it is the '2'. If the digit in that decimal place is 4 or less you round down and if that digit were 5 or more you round up. Because the fourth decimal is 4 or less the number 9.5482 is rounded down to 9.548.
