Use the formula C = 9 5 ( F − 32 ) to convert Fahrenheit to Celsius.
Substitute F = 131 into the formula: C = 9 5 ( 131 − 32 ) .
Calculate the Celsius temperature: C = 9 5 ( 99 ) = 55 .
The temperature in Celsius is 55° C .
Explanation
Understanding the Problem We are given a temperature of 131°F and asked to convert it to Celsius. We are also given four possible answers: 65°C, 55°C, 90°C, and 75°C.
Stating the Conversion Formula To convert Fahrenheit to Celsius, we use the formula: C = 9 5 ( F − 32 ) where C is the temperature in Celsius and F is the temperature in Fahrenheit.
Applying the Formula Now, we substitute the given Fahrenheit temperature, F = 131 , into the formula: C = 9 5 ( 131 − 32 ) C = 9 5 ( 99 ) C = 5 × 11 C = 55
Finding the Answer Therefore, 131°F is equal to 55°C. Comparing this result with the given options, we find that 55°C is one of the choices.
Examples
Imagine you're baking a cake and the recipe is in Fahrenheit, but your oven displays temperature in Celsius. Converting Fahrenheit to Celsius is essential to set your oven to the correct temperature and bake the cake perfectly. This conversion is also useful when traveling to countries that use Celsius, helping you understand weather forecasts and set appropriate thermostats.
To convert 131°F to Celsius, we use the formula C = 9 5 ( F − 32 ) , resulting in 55° C . Therefore, the correct answer is 55°C .
