The formula $C = \frac { 5 } { 9 } ( F - 32 )$ converts temperatures in the Fahrenheit scale to the Celsius scale. Find the equivalent Celsius temperature for the Fahrenheit temperature 68°F.
A) 154°C
B) 56°C
C) 65°C
D) 20°C

Plugging 68 for F in the formula $C = \frac { 5 } { 9 } ( F - 32 )$, we get $C = \frac { 5 } { 9 } ( 68 - 32 ) = \frac { 5 } { 9 } \times 36 = 20$, so 68°F is equivalent to 20°C.

The Formula C=59(F−32)C = \frac { 5 } { 9 } ( F - 32 )C=95​(F−32)

The Formula $C = \frac { 5 } { 9 } ( F - 32 )$
