the temperature in some region of alaska equals 12°f. convert this temperature to celsius.

Explanation:

Step1: Recall conversion formula

The formula to convert Fahrenheit ($F$) to Celsius ($C$) is $C=\frac{5}{9}(F - 32)$.

Step2: Substitute given value

Substitute $F = 12$ into the formula: $C=\frac{5}{9}(12 - 32)$.

Step3: Calculate the value inside parentheses

First, calculate $12-32=-20$. So, $C=\frac{5}{9}\times(-20)$.

Step4: Multiply

$C=\frac{-100}{9}\approx - 11.11$.

Answer:

$-11.11^{\circ}C$
