Final answer:
Diana's fever of 40°C is equivalent to 104°F. To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9/5 and then add 32.
Step-by-step explanation:
To convert a temperature from Celsius to Fahrenheit, you can use the following formula: F = (C × 9/5) + 32, where 'F' represents the Fahrenheit temperature and 'C' is the Celsius temperature.
In the case of Diana, who has a fever of 40°C, you would calculate her temperature in Fahrenheit as follows:
Step 1: Multiply the Celsius temperature by 9/5.
40 × 9/5 = 72
Step 2: Add 32 to the result of step 1 to get the temperature in Fahrenheit.
72 + 32 = 104°F
Therefore, Diana's fever of 40°C is equivalent to 104°F.
