Answer :
- Convert 425°F to Celsius using the formula: ${ }^{\circ} C = \frac{{^{\circ} F - 32}}{{1.8}}$.
- Substitute 425 for ${ }^{\circ} F$: ${ }^{\circ} C = \frac{{425 - 32}}{{1.8}} = \frac{{393}}{{1.8}}$.
- Calculate the result: ${ }^{\circ} C = 218.333...$.
- Round to one decimal place: The temperature in Celsius is approximately $\boxed{218.3}$.
### Explanation
1. Problem Analysis
Let's analyze the given questions. We have three sub-problems here:
1. **Question 1.1.2:** We need to find out how many batches of cupcakes Lihle needs to make to get 120 cupcakes. However, we don't know how many cupcakes one batch makes. Without this information, we can't solve this problem.
2. **Question 1.1.3:** We need to determine how many litres of milk are required to make 120 cupcakes. Again, we don't know how much milk is needed per cupcake, so we can't solve this without more information.
3. **Question 1.1.4:** We need to convert a temperature from Fahrenheit to Celsius. We have the formula: ${ }^{\circ} C=\left({ }^{\circ} F-32\right) \div 1.8$. We can solve this one!
2. Fahrenheit to Celsius Conversion
Let's solve question 1.1.4, which asks us to convert $425^{\circ} F$ to ${ }^{\circ} C$. We use the formula:
$${ }^{\circ} C = \frac{{^{\circ} F - 32}}{{1.8}}$$
Substitute ${ }^{\circ} F = 425$ into the formula:
$${ }^{\circ} C = \frac{{425 - 32}}{{1.8}}$$
$${ }^{\circ} C = \frac{{393}}{{1.8}}$$
Now, we perform the division:
$${ }^{\circ} C = 218.333...$$
Rounding to one decimal place, we get:
$${ }^{\circ} C \approx 218.3$$
So, $425^{\circ} F$ is approximately equal to $218.3^{\circ} C$.
3. Final Answer
Since we don't have enough information to answer questions 1.1.2 and 1.1.3, we can only provide an answer for question 1.1.4.
The temperature Danielle should set the oven to is approximately $218.3^{\circ} C$.
### Examples
Temperature conversion is a common task in cooking and baking. Recipes from different countries might use different temperature scales (Fahrenheit or Celsius). Knowing how to convert between these scales ensures you can accurately follow any recipe, regardless of its origin. This is also useful in many other fields, such as science and engineering, where precise temperature measurements are crucial.
