Question

The temperature of a room is ${77}^{o}F.$ What would it be on the Celsius scale?

• A. ${25}^{o}C$
• B. ${45}^{o}C$
• C. ${60}^{o}C$
• D. ${350}^{o}C$

Answer 1

The correct option is A ${25}^{o}C$

Given,
Temperature of a room is ${77}^{o}F$
$\frac{C}{100}=\frac{F-32}{180}$
$\frac{C}{100}=\frac{(77-32)}{180}$
$C=\frac{45}{180}\times 100={25}^{o}C$.
