To solve this problem, you should first convert all temperatures to one temperature scale. I'll use the formula to convert Fahrenheit to Celsius. It is C = 5/9(F - 32), where F is the degrees Fahrenheit.
Let's start converting.
C = 5/9(-5 - 32) C = 5/9(-37) C = -185/9 C = -20.6°
C = 5/9(40 - 32) C = 5/9(8) C = 40/9 C = 4.4°
Now let's arrange them from least to greatest: -20.6°C, -8°C, 4.4°C, 10°C.
