The temperature of human body is `98.4^(@)F`. Calculate the temperature in `""^(@)C` and in Kelvin.

Explanation

To convert the temperature from Fahrenheit to Celsius and then to Kelvin, we can follow these steps:

### Step 1: Convert Fahrenheit to Celsius
The formula to convert Fahrenheit (°F) to Celsius (°C) is:
\[ T(°C) = \frac{5}{9} (T(°F) - 32) \]
Given \( T(°F) = 98.4 \):
\[ T(°C) = \frac{5}{9} (98.4 - 32) \]
\[ T(°C) = \frac{5}{9} (66.4) \]
\[ T(°C) = \frac{332}{9} \approx 36.8 \]
So, the temperature in Celsius is approximately \( 36.8 °C \).

### Step 2: Convert Celsius to Kelvin
The formula to convert Celsius to Kelvin is:
\[ T(K) = T(°C) + 273.15 \]
Using the value we found for Celsius:
\[ T(K) = 36.8 + 273.15 \]
\[ T(K) = 309.95 \]
So, the temperature in Kelvin is approximately \( 309.95 K \).

### Final Answers:
- Temperature in Celsius: \( 36.8 °C \)
- Temperature in Kelvin: \( 309.95 K \)
