The image shows a thermometer. What is the temperature displayed?

Solution:

The thermometer has markings for 20, 10, 0, -10, and -20 degrees Celsius.

The red liquid level is below the 0°C mark.

Let's count the divisions between 0°C and -10°C. There are 10 divisions.

This means each division represents \( \frac{10 - 0}{10} = 1 \) degree Celsius.

The red liquid level is at the 6th division below 0°C.

Therefore, the temperature is \( 0 - 6 \times 1 \text{°C} = -6 \text{°C} \).

Answer: -6°C.
