1. The problem is to convert the given mixed expression involving time (28 horas) and a fraction into a single value or expression. 2. Given: 28 horas, and possibly a fraction $\frac{125}{6}$; the context implies converting or comparing times or values. 3. First, clarify what the user wants to achieve: if converting hours to a fraction or multiplying these quantities. 4. If we assume the question is to calculate $28 \times \frac{125}{6}$, then: $$28 \times \frac{125}{6} = \frac{28 \times 125}{6} = \frac{3500}{6} = \frac{1750}{3} \approx 583.33$$ 5. This means 28 hours multiplied by $\frac{125}{6}$ equals approximately 583.33 (units depending on the context). 6. Without further context, this is the simplified evaluation of the given numbers.
