Hello to all friends of the mymathforum I'm new in this community. Thank you! I would like to help me with this exercise, I have to deliver today: The temperatures in a 24 hour period between 4 ° F and 23 ° F, What was the variation in Celsius? (use F = 9/5 C +32)

Or use the equivalent formula C = 5(F  32)/9.
