Question

convert 120.2° F into °C

Answer 1

ANSWER WITH STEPS

To convert the given temperature from Fahrenheit to Celsius, use this formula: 
$C=(\frac{5}{9})(F-32)$
where, $C$ is the temperature in Celcius, and $F$ is the temperature in Fahrenheit. 

$C$
$=(\frac{5}{9})(F-32)$
$=(\frac{5}{9})(120.2-32)$
$=\frac{5}{9}*88.2$
$=\frac{5}{9}*\frac{882}{10}$
= 49 °C

∴ The temperature in Celsius is 49 °C.
