A car factory made 44 cars with a sunroof and 1 car without a sunroof. What is the ratio of the number of cars without a sunroof to the total number of cars?

To find the ratio of the number of cars without a sunroof to the total number of cars, follow these steps:

1. **Determine the number of cars without a sunroof:**  
   The problem states that 1 car was made without a sunroof.

2. **Calculate the total number of cars made:**  
   Total number of cars = Number of cars with a sunroof + Number of cars without a sunroof  
   \[
   \text{Total number of cars} = 44 + 1 = 45
   \]

3. **Find the ratio of cars without a sunroof to the total number of cars:**  
   The ratio is:
   \[
   \frac{\text{Number of cars without a sunroof}}{\text{Total number of cars}} = \frac{1}{45}
   \]

So, the ratio of the number of cars without a sunroof to the total number of cars is **1:45**.
