Final answer:
The 'toCelsius' function converts Fahrenheit to Celsius using the formula celsius = 5.0/9.0 * (fahrenheit - 32). An example is converting 88°F to approximately 31.1°C.
Step-by-step explanation:
To define a function called toCelsius that returns the Celsius temperature given a Fahrenheit temperature, one can use the conversion formula celsius = (5.0/9.0) × (fahrenheit - 32). To define a function called toCelsius that returns the Celsius temperature given a Fahrenheit temperature, you can use the conversion formula: celsius = 5.0/9.0 * (fahrenheit - 32). This formula uses the relationship between Fahrenheit and Celsius scales to convert temperatures. For example, if the Fahrenheit temperature is 68 degrees, you can plug it into the formula to find the equivalent Celsius temperature:
Celsius = 5.0/9.0 * (68 - 32)Celsius = 5.0/9.0 * 36Celsius = 20 degreesFor example, if you want to convert 88°F to Celsius, the function will calculate toCelsius(88) = 5.0/9.0 × (88 - 32), which results in approximately 31.1°C. It is worth noting that there is an interesting fact from LibreTexts stating there is only one temperature where Fahrenheit and Celsius are the same: -40°C = -40°F.
