Final answer:
To convert a 40.0 these degrees Fahrenheit decrease to Celsius, we use the conversion formula, which gives us an approximately 22.2 degrees Celsius decrease.
Step-by-step explanation:
In order to convert the decrease in Fahrenheit to Celsius we use the formula C = (F - 32) * 5/9. This formula is used to convert Fahrenheit to Celsius. So, first we subtract 32 from the Fahrenheit decrease, which would give -8. From this, we multiply it by 5/9 which yields approximately -4.44. Therefore, a 40.0ºF decrease is approximately equivalent to a 22.2 degrees Celsius decrease.
