$45^{\circ} F = {23.4}^{\circ} C$ $45 ^@F = 23.4 ^@C$

Explanation:

$45^{\circ} F$ $45 ^@F$ is $(45 - 32) = 13 F^{\circ}$ $(45-32) = 13 F^@$ above freezing (water freezes at $32^{\circ} F$ $32 ^@F$ )

$180 F^{\circ} = 100 C^{\circ}$ $180 F^@ = 100 C^@$ (difference between freezing and boiling on each scale)

$\Rightarrow 1 F^{\circ} = \frac{18}{10} C^{\circ}$ $rArr 1 F^@ = 18/10 C^@$

$13 F^{\circ} = 13 \times \frac{18}{10} C^{\circ} = 23.4 C^{\circ}$ $13 F^@ = 13xx18/10 C^@ = 23.4 C^@$

$23.4 C^{\circ}$ $23.4 C^@$ above freezing is ${23.4}^{\circ} C$ $23.4 ^@C$
