Rewrite the formula to convert Fahrenheit to Celsius using fractions instead of decimal numbers.

Given the formula for converting Celsius to Fahrenheit:

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

Now, solve for [tex] C [/tex] to rewrite the formula for converting Fahrenheit to Celsius.

Answer :

To convert temperatures from degrees Fahrenheit to degrees Celsius, we will start with the given formula for converting Celsius to Fahrenheit:

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

We need to rearrange this formula to solve for [tex]\( C \)[/tex].

1. Subtract 32 from both sides:
[tex]\[
F - 32 = \frac{9}{5}C
\][/tex]

2. Multiply both sides by the reciprocal of [tex]\(\frac{9}{5}\)[/tex], which is [tex]\(\frac{5}{9}\)[/tex], to isolate [tex]\( C \)[/tex]:
[tex]\[
C = \frac{5}{9}(F - 32)
\][/tex]

So, the formula to convert degrees Fahrenheit to degrees Celsius is:

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

This equation allows you to take a temperature in Fahrenheit (F) and calculate the equivalent temperature in Celsius (C) by subtracting 32 from the Fahrenheit value, then multiplying by [tex]\(\frac{5}{9}\)[/tex].
