To convert a temperature from Fahrenheit to Celsius using the formula [tex]\( C = \frac{5}{9}(F - 32) \)[/tex], we follow a series of steps. We will apply these steps to convert [tex]\( 68^{\circ} F \)[/tex] to Celsius.
1. Identify the given temperature in Fahrenheit:
[tex]\[
F = 68^{\circ} F
\][/tex]
2. Subtract 32 from the Fahrenheit temperature:
[tex]\[
68 - 32 = 36
\][/tex]
3. Multiply the result by [tex]\( \frac{5}{9} \)[/tex]:
[tex]\[
C = \frac{5}{9} \times 36
\][/tex]
4. Calculate the multiplication:
[tex]\[
C = 20
\][/tex]
Thus, [tex]\( 68^{\circ} F \)[/tex] is equivalent to [tex]\( 20^{\circ} C \)[/tex].
So, [tex]\( 68^{\circ} F = 20^{\circ} C \)[/tex].
