Calculate the value of the error (only) with two decimal places for: (5.5 +/- 0.2) / (1.6 +/- 0.2) enter the answer without +/- sign.

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
