Question

Convert $40°C$ to the Fahrenheit scale.

Answer 1

Step 1: We have

The temperature on the Celsius scale$=C=40°C$.

Step 2: To convert it to the Fahrenheit scale

$\frac{C}{5}=\frac{F-32}{9}$

$\frac{40}{5}=\frac{F-32}{9}$

$8=\frac{F-32}{9}$

$F-32=\left(8\times 9\right)$

$F-32=72$

So, $F=72+32$

$F=104°F$

Hence, the required temperature on the Fahrenheit scale is $104°F$.
