If x = 9.6, y= 3.60 and z = 5, Find the percentage error in the calculation of ^{(x+y)}/_{z}, giving your answer to three significant figures.

maximum value = ^{(9.65 + 3.605)}/_{4.5} = 2.9456minimum value = ^{(9.55 + 3.595)}/_{5.5} = 2.39actual value = ^{(9.6 + 3.60)}/_{5} = 2.64absolute error = ^{(2.9456 - 2.39)}/_{2} = 0.2778 percentage error =^{ 0.2778}/_{2.64} x 100% = 10.5%
