In the Car and Truck Expenses Worksheet, the Percent of business use (line 9) is computed incorrectly.

The "Percent of business use" (line 9) is computed by dividing line 6 by line 5c. In my case line 6 is 516 and line 5c is 4100. When I divide the numbers I get 12.6%. In the form line 9 shows 8.39%. is this ok to submit with this error?
