the air pressure was 101.3 kPa, but the weatherman said it was 1001.3 kPa. What is the percentage error

percentage error = 888.45 %

Explanation:

We calculate the percentage error using the following formula:

percentage error = [ (estimated number - actual number) / actual number) * 100

percentage error = [ (1001.3 - 101.3) / 101.3] * 100

percentage error = 888.45 %
