## Thinking Mathematically (6th Edition)

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 = 475 $C=\frac{5}{9}(F-32) = \frac{5}{9}(475-32) = \frac{5}{9}(443) = 2215 \div 9 = 246.11$ = 246.1 (rounding) For F = 475, C = 246.1
