Determine the percent error in this approximate value. (There are 365.24 days in one year.)

Answer 1

The actual number of days in a complete orbital revolution is not quite 365.24. A more accurate value is
365 + 97/400 = 365.2425

(There are 97 leap years in a 400 year period. Century years are only leap years if they are divisible by 400)

The relative error in the number you provided is
0.0025/365.24 = 7*10^-6, or .0007%

Answer 2

the answer is .446%
