1. The problem is to convert temperature from Celsius to Fahrenheit. 2. We use the formula for conversion: $$F=\frac{9}{5}C+32$$ where $C$ is Celsius and $F$ is Fahrenheit. 3. Substitute $C=25$ into the formula: $$F=\frac{9}{5}\times 25+32$$ 4. Calculate multiplication first: $$\frac{9}{5}\times 25=9\times 5=45$$ 5. Add 32 to 45: $$45 + 32 = 77$$ 6. Therefore, 25 degrees Celsius equals 77 degrees Fahrenheit. Final answer: $77$ Fahrenheit
