Answer:
178.03 rounded to the nearest ones is just 178.
Explanation:
When rounding, you look to the value after the number you are trying to round to. In this case, you are rounding the nearest ones which is 8 in your problem. The value after 8 is 0 so 8 stays the same. You only want to round up if the next value is above or equal to 5.
178
The ones digit is shown below in bold. It is the 8.
178.03
Drop the digits to the right of the 8.
Since the first digit to the right of the 8 is 0, and not 5 or higher, the 8 remains as 8.
