Question

como converter 78ºF em ºC

Answer 1

Tc / 5 = Tf - 32 / 9

Tc / 5 = 78 - 32 / 9

Tc / 5 = 46 / 9

9 · Tc = 46 · 5

9 Tc = 230

Tc = 230 / 9

Tc = 25,55 °C

Answer 2

$\frac{T(C) }{5} = \frac{T(F)-32}{9}\\\\ \frac{T(C) }{5} =  \frac{78-32}{9}\\\\ \frac{T(C) }{5} =5,1 \\\\ T(C) = 5,1 * 5\\ T(C) = 25,5$
