1.1.2. How many batches of cupcakes does Lihle need to make to produce 120 cupcakes?

1.1.3. How many liters of milk does Lihle need to make 120 cupcakes?

1.1.4. Lihle's oven uses [tex]^{\circ} C[/tex], but the recipe tells her to set the oven to [tex]425^{\circ} F[/tex]. What temperature should Lihle set the oven to in [tex]^{\circ} C[/tex]?

[tex]\left(^{\circ} C=\left(^{\circ} F-32\right) \div 1.8\right)[/tex]

- Substitute the Fahrenheit temperature into the conversion formula.
- Subtract 32 from the Fahrenheit temperature.
- Divide the result by 1.8 to obtain the Celsius temperature.
- The temperature in Celsius is approximately $\boxed{218.3}$.

### Explanation
1. Understanding the problem
We need to convert 425 degrees Fahrenheit to degrees Celsius using the formula: $$°C = (°F - 32) ÷ 1.8$$

2. Applying the formula
Substitute 425 for °F in the formula:$$°C = (425 - 32) ÷ 1.8$$

3. Simplifying the expression
Calculate the value inside the parentheses:$$°C = (393) ÷ 1.8$$

4. Calculating the Celsius temperature
Perform the division:$$°C = 218.333...$$

5. Final result
Rounding to one decimal place, we get:$$°C ≈ 218.3$$

### Examples
Temperature conversion is a common task in cooking, science, and everyday life. For example, if you are following a recipe from another country, you might need to convert the oven temperature from Fahrenheit to Celsius. Understanding how to convert between temperature scales allows you to accurately follow instructions and achieve the desired results.
