To convert Fahrenheit to Celsius, you have to do:
[tex] C \° = (F \° - 32\°) \times\frac{5}{9} [/tex]
Put in the number(s) into the formula:
[tex] C\° = (37\° - 32\°) \times \frac{5}{9} [/tex]
Subtract:
[tex] 37\°-32\° = 5\° [/tex]
Now multiply by [tex] \frac{5}{9} [/tex]
[tex] 5 \times \frac{5}{9} =\frac{25}{9} = 2 \frac{7}{9} \° \rightarrow 2.7778 \° = 2.8 \°[/tex]
Your answer is 2.7778° ⇔ 2.8° ⇔ 2 7/9°
