Answer 2

Answer: Negative 20.75

Explanation:

The question simply wants us to convert the temperature shown by the thermometer to decimal. We should note that the temperature shown is Negative 20 and three-fourths degrees.

First, we convert 3/4 to decimal. This will be:

= 3/4 = 0.75.

Therefore, -20 3/4 = -20.75
