The formula to convert Fahrenheit to Celsius is C = 5/9 (F-32).
convert 12C to Fahrenheit
We replace 12 with C in the formula
[tex]12 = \frac{5}{9} (F-32)[/tex]
Now multiply the fraction inside the parenthesis
[tex]12 = \frac{5}{9}F-\frac{5}{9}*32[/tex]
[tex]12 = \frac{5}{9}F-\frac{160}{9}[/tex]
Add the fraction on both side
[tex]12+\frac{160}{9} = \frac{5}{9}F[/tex]
[tex] \frac{108+160}{9} = \frac{5}{9}F[/tex]
[tex] \frac{268}{9} = \frac{5}{9}F[/tex]
multiply by 9/5 on both sides
[tex] \frac{268}{9} *\frac{9}{5} = F[/tex]
[tex] \frac{268}{5} = F[/tex]
F= 53.6
So Fahrenheit = 53.6
When we round to nearest degree it becomes 54
