Answer for screen readers
The temperature in Celsius is $20$ degrees.
Steps to Solve
- Identify the given temperature in Fahrenheit
Let's say the temperature you want to convert is $F$. For example, if $F = 68$ degrees Fahrenheit.
- Subtract 32 from the Fahrenheit temperature
To start the conversion process, subtract 32 from the given temperature:
$$ F - 32 $$
For our example, it would be:
$$ 68 - 32 = 36 $$
- Multiply the result by $\frac{5}{9}$
Next, multiply the result from step 2 by $\frac{5}{9}$ to get the temperature in Celsius:
$$ C = \frac{5}{9} \times (F - 32) $$
Using our example:
$$ C = \frac{5}{9} \times 36 $$
- Calculate the Celsius temperature
Now, compute the multiplication:
$$ C = \frac{5 \times 36}{9} $$
This simplifies to:
$$ C = \frac{180}{9} = 20 $$
So, the final temperature in Celsius is 20 degrees.
The temperature in Celsius is $20$ degrees.
