#### Answer

42°C (rounded), 4°C (rounded)

#### Work Step by Step

Given, Hummingbirds have a normal body temperature of 107 °F. But on cold nights they go into a state of torpor where their body temperature drops to 39 °F.
To find 107 °F and 39 °F in Celsius
107 °F
C = (5 (F-32))/9 = (5 (107-32))/9 = (5(75))/9 = 375/9 = 41.66
107 °F = 42°C (rounded)
Therefore the 107 °F temperature in Celsius is 42 °C
39 °F
C = (5 (F-32))/9 = (5 (39-32))/9 = (5(7))/9 = 35/9 = 3.88
39 °F = 4°C (rounded)
Therefore the 39 °F temperature in Celsius is 4 °C
