Question

Um termômetro graduado na escala Fahrenheit indica -86°F. Qual o valor dessa mesma temperatura na escala Celsius? 



​

Answer 1

$\frac{TC }{5}$ = $\frac{TF - 32}{9}$

$\frac{TC}{5}$ = $\frac{-86 - 32}{9}$

$\frac{TC}{5}$ = $\frac{-118}{9}$

TC × 9 = - 118 × 5

TC × 9 = - 590

TC = $\frac{-590}{9}$

TC = - 65,55° C
