Answer :
- Substitute the given Fahrenheit temperature ($425^{\circ}F$) into the conversion formula.
- Calculate the difference: $425 - 32 = 393$.
- Divide the result by 1.8: $393 \div 1.8 = 218.333...$.
- Round to one decimal place: The oven temperature in Celsius is $\boxed{218.3^{\circ}C}$.
### Explanation
1. Understanding the Problem
We are given a temperature in Fahrenheit, $425^{\circ}F$, and we need to convert it to Celsius using the formula:$$^{\circ}C = (^{\circ}F - 32) \div 1.8$$
2. Applying the Formula
Substitute the given Fahrenheit temperature into the formula:$$^{\circ}C = (425 - 32) \div 1.8$$
3. Performing Subtraction
Calculate the value inside the parentheses:$$425 - 32 = 393$$
4. Performing Division
Now, divide the result by 1.8:$$^{\circ}C = 393 \div 1.8 = 218.333...$$
5. Final Answer
Round the result to one decimal place, as is conventional for oven temperatures:$$^{\circ}C \approx 218.3$$Therefore, Lihle should set her oven to approximately $218.3^{\circ}C$.
### Examples
Imagine you're baking a cake using a recipe from another country. The recipe lists the oven temperature in Fahrenheit, but your oven uses Celsius. Converting the temperature ensures your cake bakes perfectly, preventing it from burning or not cooking properly. This conversion is also useful when following scientific instructions or conducting experiments that require precise temperature settings. Knowing how to convert between Fahrenheit and Celsius allows for accurate and consistent results in cooking, science, and other fields.
