Question

using the proper equation, convert -25.5°f to °c.

Explanation:

Step1: Recall the conversion formula

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

Step2: Substitute the given value

Substitute $F=-25.5$ into the formula: $C=\frac{5}{9}(-25.5 - 32)$.

Step3: Calculate the value inside the parentheses

First, calculate $-25.5-32=-57.5$.

Step4: Multiply by $\frac{5}{9}$

$C=\frac{5}{9}\times(- 57.5)\approx - 31.94$.

Answer:

$-31.94$
