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
