Convert 45 degrees Fahrenheit to Celsius.
Understand the Problem
The question is asking how to convert a temperature from Fahrenheit to Celsius. To solve this, we will apply the conversion formula: C = (F - 32) × 5/9, where F is the temperature in Fahrenheit and C is the temperature in Celsius.
Answer
The temperature in Celsius is \( C = 20 \).
Answer for screen readers
The temperature in Celsius is ( C = 20 ).
Steps to Solve
- Identify the temperature in Fahrenheit
Choose the temperature value you want to convert from Fahrenheit to Celsius. For example, let’s say ( F = 68 ).
- Apply the conversion formula
Use the conversion formula to change Fahrenheit to Celsius. The formula is:
$$ C = (F - 32) \times \frac{5}{9} $$
- Substitute the Fahrenheit value into the formula
Insert the value of ( F ) you identified in step 1 into the formula. For our example:
$$ C = (68 - 32) \times \frac{5}{9} $$
- Perform the calculations
First, calculate ( 68 - 32 = 36 ).
Now, multiply by ( \frac{5}{9} ):
$$ C = 36 \times \frac{5}{9} $$
- Final calculation
Calculate ( 36 \times \frac{5}{9} = 20 ).
Thus, the temperature in Celsius is:
$$ C = 20 $$
The temperature in Celsius is ( C = 20 ).
