Question 138
On a winter day the temperature at a place in Himachal Pradesh was $-{16}^{\circ }C$. Convert it in degree Fahrenheit ${(}^{\circ }F)$ by using the formula.
$\frac{C}{5}=\frac{F-32}{9}$

Answer 1

Given, temperature of Himachal Pradesh $=-{16}^{\circ }C$
$\because$ $\frac{C}{5}=\frac{F-32}{9}$

$\Rightarrow \frac{-16}{5}=\frac{F-32}{9}$
$\Rightarrow F-32=-\frac{144}{5}$
$\Rightarrow F=32-\frac{144}{5}$
$\Rightarrow F=\frac{160-144}{5}$
$=\frac{16}{5}={3.2}^{\circ }F$
