Explanation:

Given the equation: The absolute uncertainty in a measurement is the term used to describe the degree of inaccuracy.

The first step is to determine the algebraic value on the numerator.

Algebraic value = 9.8 – 231

= 7.49

The absolute uncertainty = absolute uncertainty = = = 0.300167

[9.8(±0.3) – 2.31(±0.01)] = 7.49(±0.300167)

The division process now is: Relative uncertainty = Relative uncertainty = ±4.007565% ,  ±7.058824%    ≅ 8%

The algebraic value = = 0.881176

≅ 0.88

The percentage of the relative uncertainty = By cross multiplying:    Finally:
