$30 f$

Step 1

This is the conversion formula for Fahrenheit to Celsius, where $T_{F}$ is temperature in Fahrenheit and $T_{C}$ is temperature in Celsius.

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

Step 2

Substitute the Fahrenheit temperature into the formula.

$\frac{5}{9} (30 - 32) C$

Step 3

Divide $5$ by $9$ .

$0.\overline{5} (30 - 32) C$

Step 4

Subtract $32$ from $30$ .

$0.\overline{5} \cdot - 2 C$

Step 5

Multiply $0.\overline{5}$ by $- 2$ .

$- 1.\overline{1} C$
