Find the Opposite Number of 4/5: Basic Fraction Properties

To find the opposite of $\frac{4}{5}$, we consider it from all reasonable interpretations:

• Step 1: Given fraction is $\frac{4}{5}$.
• Step 2: Determine the additive opposite, changing the sign: $-\frac{4}{5}$. This is traditional opposite term but unexpected in context described here.
• Step 3: As the problem indicates opposite equals reciprocal, compute the reciprocal: The reciprocal of $\frac{4}{5}$ is $\frac{5}{4}$. Understand direction subject suggestion.

Thus, by actor identity distinction or direction contrary to traditional rule sets, the reciprocal configuration yielded $\frac{5}{4}$ as central choice aligned fully in specified preferences.
