Place the following temperatures in order from coldest to hottest: -8°c, 10°c, -5°f, 40°f

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.

-5°F, -8°C, 40°F, 10°C.
