To determine the percent decrease of a number would be calculated like this. $$\text{Percentage Decrease} = \\ \dfrac{\text{Starting Value} - \text{Final Value}}{\left|\text{Starting Value}\right|} \times 100$$, Subtract starting value minus final value, Divide that amount by the absolute value of the starting value. An increase in oxidation number corresponds to oxidation, and a decrease to reduction. With 1 as the numerator and 3 as the denominator, the fraction part of the mixed number is 1/3. It is similar to finding percentage increase or percentage decrease but it doesn't label the change as an increase or a decrease. The estimate includes WEP reduction.
