Which of the following is the correct Fahrenheit temperature equivalent to 37.8 °C?

• A. 100 °F
• B. 99.9 °F
• C. 75.4 °F
• D. 86 °F

Answer: (B)

Verified step by step guidance

1. Recall the formula to convert Celsius temperature (\( T_C \)) to Fahrenheit temperature (\( T_F \)): \[ T_F = \frac{9}{5} T_C + 32 \]
2. Identify the given Celsius temperature: \( T_C = 37.8^\circ C \).
3. Substitute \( T_C = 37.8 \) into the conversion formula: \[ T_F = \frac{9}{5} \times 37.8 + 32 \]
4. Calculate the multiplication \( \frac{9}{5} \times 37.8 \) first, then add 32 to the result to find \( T_F \).
5. Compare the calculated Fahrenheit temperature with the given options to determine which one matches the converted value.
