Calculating the Relative Error & Improving Accuracy of Measurements

[usamahashimi]

Hi
Can anyone help me to solve the following question;

Q: You measure the length of two rods using a meter ruler and find;
Length 1 = [2.000+/-1x10^-3] meter
Length 2 = [0.100+/-1x10^-3] meter
find the relative error (fractional error), which value is more accurate? How can we improve the accuracy of the least accurate reading?

Note: in both equations the +/- is written above and below of each other without the '/' sign.

Thanks.
