Answer :
- Questions 1.1.2 and 1.1.3 cannot be answered because the number of cupcakes per batch and the amount of milk per cupcake are not provided.
- To convert $425^{\circ} F$ to Celsius, use the formula ${ }^{\circ} C=\left({ }^{\circ} F-32\right) \div 1.8$.
- Substitute $425$ for ${ }^{\circ} F$: ${ }^{\circ} C = (425 - 32) \div 1.8 = 393 \div 1.8 = 218.333...$.
- The oven should be set to approximately $\boxed{218.33^{\circ} C}$.
### Explanation
1. Understanding the Problem
Let's break down this problem into three smaller parts to make it easier to solve. We'll start by identifying what we need to find out for each question.
2. Question 1.1.2 Analysis
First, we need to know how many cupcakes are in one batch to answer question 1.1.2. Unfortunately, this information is not provided in the problem. Therefore, we cannot determine the number of batches needed to produce 120 cupcakes.
3. Question 1.1.3 Analysis
Next, for question 1.1.3, we need to know how many litres of milk are required per cupcake. Again, this information is not provided, so we cannot calculate the total litres of milk needed for 120 cupcakes.
4. Question 1.1.4 Solution
Finally, for question 1.1.4, we need to convert 425 degrees Fahrenheit to Celsius using the given formula: ${ }^{\circ} C=\left({ }^{\\\circ} F-32\right) \div 1.8$. Substituting ${ }^{\circ} F = 425$ into the formula, we get: ${ }^{\circ} C = (425 - 32) \div 1.8 = 393 \div 1.8 = 218.333...$
5. Final Answer for 1.1.4
Therefore, Lihle should set the oven to approximately $218.33^{\circ} C$.
### Examples
Temperature conversion is essential in cooking, baking, and various scientific applications. For example, when following a recipe from another country, you might need to convert oven temperatures from Fahrenheit to Celsius or vice versa. This ensures that you are using the correct temperature for the recipe to turn out as expected. Understanding temperature conversions is also crucial in fields like chemistry and physics, where experiments often require precise temperature control.
