Question

A recipe calls for an oven to be preheated to 400 °F. What is the approximate temperature of the preheated oven in Celsius degrees? °C = 5/9(°F − 32)

Answer 1

The approximate temperature of the preheated oven is 204 °C.

Explanation:

Here, the given temperature in Fahrenheit = 400 °F

Let us assume the given temperature in Celsius = C

Now, the relation between the two measure of temperature is given as:

`F =( (9)/(5) )C + 32`

According to the question:

`400  =( (9)/(5))C + 32 \\\implies ( (9)/(5))C =  400 - 32  = 368\\or, C  = 368 *(5)/(9)   =204.4`

Or, C = 204.4°C

Hence, the approximate temperature of the preheated oven is 204 °C.
