#### Answer

$-13^{\circ}~F$

#### Work Step by Step

$F = \frac{9}{5}C+32$
We can use this formula to convert from Celsius to Fahrenheit. It is given in the question that $C = -25$ since the temperature on the Celsius scale is $-25^{\circ}~C$.
$F = \frac{9}{5}C+32$
$F = \frac{9}{5}(-25)+32$
$F = (-45)+32$
$F = -13$
The temperature on the Fahrenheit scale is $-13^{\circ}~F$
