What is the temperature in degrees Celsius equivalent to 71 degrees Fahrenheit?

• A. 25.0 °C
• B. 18.3 °C
• C. 32.8 °C
• D. 21.7 °C

Answer: (D)

Verified step by step guidance

1. Recall the formula to convert Fahrenheit (F) to Celsius (C): \( C = \frac{5}{9} (F - 32) \).
2. Substitute the given Fahrenheit temperature (71 °F) into the formula: \( C = \frac{5}{9} (71 - 32) \).
3. Calculate the difference inside the parentheses: \( 71 - 32 \).
4. Multiply the result by 5 and then divide by 9 to find the Celsius temperature: \( C = \frac{5}{9} \times (\text{difference}) \).
5. Interpret the final value as the temperature in degrees Celsius equivalent to 71 °F.
