  1. ## error and percent error
  
  Ugh, greatest possible error and percent error is not my best friend.
  
  How do I solve these problems...Ive never covered this stuff in school.

  Hi LivinLife,
  
  What problems? I don't see any.
  
  The Greatest Possible Error of a measurement is one half of the unit of measure to which the measure is being rounded.
  
  Example: If you are measuring a length using inches, the greatest possible error would be 1/2 inch. If you measured in meters, the greatest possible error would be 50 cm (1/2 meter).
  
  Per Cent Error = $\frac{\text{Observed value - True Value}}{\text{True Value}} \times 100$

  haha sorry...
  um the questions im trying to figure out are:
  
  Find the greatest possible error for the measurement 0.991g
  Find the percent error for 2cm (round to the nearest hundredth)
