Question

The temperature on the Celsius scale is ${25}^{\circ }\text{C}$. What is the corresponding temperature on the Fahrenheit scale?

• A. ${40}^{\circ }\text{F}$
• B. ${77}^{\circ }\text{F}$
• C. ${50}^{\circ }\text{F}$
• D. ${45}^{\circ }\text{F}$

Answer 1

The correct option is B ${77}^{\circ }\text{F}$

$\frac{C}{5}=\frac{F-32}{9}\Rightarrow \frac{25}{5}=\frac{F-32}{9}$
$\Rightarrow F={77}^{\circ }\text{F}$
