Answer:102.2 degrees Fahrenheit
Explanation: When you want to convert from Celsius to Fahrenheit a simple formula to use is
F=(C * 1.8) + 32
F=(39*1.8)+32
F=102.2
C stand for Celsius
When you convert Fahrenheit to Celsius you start with a temperature in Fahrenheit i.e 102.2 and then subtract 32 from the value of Fahrenheit i.e (102.2 - 32 = 70.2
Then divide this answer by 1.8 i.e 70.2 / 1.8 = 39 , hence you can see that we do vice versa instead of multiplying with 1.8 we divide by it , if we convert back from Celsius to Fahrenheit and we also subtract 32 instead of adding
