Answer

-35 C

Work Step by Step

Here we need to convert a Fahrenheit temperature to its equivalent temperature on the Celsius scale. $C=\frac{5}{9}(F-32)$, where F = Fahrenheit temperature and C = Celsius temperature. F = -31 $C=\frac{5}{9}(F-32) = \frac{5}{9}(-31-32) = \frac{5}{9}(-63) = 5 \times (-7) = -35 $ For F = -31, C = -35
