The temperature which has same numerical valle UCelsius and Fahrenheit scale is(a) 273x) -40(b) -273(d) 40

Answer»

°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
