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
