Final answer:
The temperatures ordered from coldest to warmest are: -23.7°F, -19.4°F, -4.5°F, 0°F, and 20°F.
Step-by-step explanation:
To order the given temperatures from coldest to warmest, we simply need to arrange the numbers in ascending order since the larger the negative number, the colder the temperature, and the larger the positive number, the warmer the temperature.
- -23.7°F
- -19.4°F
- -4.5°F
- 0°F
- 20°F
Therefore, the temperatures in order from coldest to warmest are: -23.7°F, -19.4°F, -4.5°F, 0°F, and 20°F.
