Question

To convert a Fahrenheit temperature to Celsius, one formula to use is F=9/5C+32, where F is the Fahrenheit temperature (in degrees) and C is the Celsius temperature. What is the Celsius temperature (to the nearest degree) when Fahrenheit temperature is 77 degrees?

Answer 1

\[77=\frac{ 9 }{ 5 }C+32\]
\[77-32=\frac{ 9 }{ 5 }C+32-32\]
\[45=\frac{ 9 }{ 5}C\]
\[\frac{ 45 }{ \frac{ 9 }{ 5 } }=\frac{ \frac{ 9 }{ 5 } }{ \frac{ 9 }{ 5 } }C\]
25=C
