For this case we have the following nominal value: 5.5 / 1.6 = 3.4 For the numerator we have the following range of values: 5.5 - 0.2 = 5.3 5.5 + 0.2 = 5.7 For the denominator we have on the other hand: 1.6 - 0.2 = 1.4, to 1.6 + 0.2 = 1.8 Therefore, making the corresponding divisions: 5.3 / 1.4 = 3.8 5.7 / 1.8 = 3.2 Thus, the error will be given by 3.8-3.4 = +0.4 3.2 - 3.4 = -0.2 answer +0.4 -0.2
