Question

Numerical- Find the temperature that has the same numerical value on the Celsius and Fahrenheit scale. please help me with the full discription.​

Answer 1

The formulas for converting between degree Celsius and degree Fahrenheit are:

°F=(°C∗9/5)+32

°C=(°F−32)∗5/9

To find the temperature when both are equal, we use an old algebra trick and just set ºF = ºC and solve one of the equations.

°C=(°C∗9/5)+32

°C−(°C∗9/5)=32

−4/5∗°C=32

°C=−32∗5/4

°C=−40

°F=(°F∗9/5)+32

°F−(°F∗9/5)=32

−4/5∗°F=32

°F=−32∗5/4

°F=−40

So the temperature when both the Celsius and Fahrenheit scales are the same is −40degrees.
