The length of a piece of stick is 1.75 m. A boy measured it as 1.80 m. Find the percentage error
4\(\frac{4}{7}\)
2\(\frac{6}{7}\)
2\(\frac{7}{9}\)
4\(\frac{7}{9}\)
Correct answer is B
Error = 1.80 - 1.75 = 0.05
%error = \(\frac{error}{original length}\)
= \(\frac{0.05 * 100}{1.75}\)
= 2.85 or 2\(\frac{6}{7}\)
