Answer
$212^{\circ}~F$
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 $C = 100$ since the temperature on the Celsius scale is $100^{\circ}~C$.
$F = \frac{9}{5}C+32$
$F = \frac{9}{5}(100)+32$
$F = 180+32$
$F = 212$
The temperature on the Fahrenheit scale is $212^{\circ}~F$
