Rewrite the formula to convert Fahrenheit to Celsius.

Given the formula for converting Celsius to Fahrenheit:
\[ F = \frac{9}{5} C + 32 \]

Find the formula to convert Fahrenheit to Celsius.

Express your answer using fractions instead of decimal numbers.

Answer :

To convert a temperature from degrees Fahrenheit to degrees Celsius, we need to rearrange the given formula, which converts Celsius to Fahrenheit:

[tex]\[ F = \frac{9}{5}C + 32 \][/tex]

Let's go through the steps to solve for [tex]\( C \)[/tex] in terms of [tex]\( F \)[/tex]:

1. Subtract 32 from both sides of the equation to eliminate the constant on the right:

[tex]\[ F - 32 = \frac{9}{5}C \][/tex]

2. Isolate [tex]\( C \)[/tex] by multiplying both sides of the equation by the reciprocal of [tex]\(\frac{9}{5}\)[/tex], which is [tex]\(\frac{5}{9}\)[/tex]:

[tex]\[ C = \frac{5}{9}(F - 32) \][/tex]

Now, we have the formula to convert Fahrenheit to Celsius:

[tex]\[ C = \frac{5}{9}(F - 32) \][/tex]

This formula allows you to convert any temperature from Fahrenheit to Celsius by plugging in the Fahrenheit value for [tex]\( F \)[/tex].
