Question

transforme 70 graus fahrenheit em graus celsius

Answer 1

A fórmula de conversão de celsius para fahrenheit é:
c/100 = f-32/180

c/100 = 70-32/180
c/100 = 38/180
180c = 3800
c = 21,11°C

Answer 2

$78\°F~~~em~~~\°C:\\\\\\ \°C = \dfrac{\°F-32}{1,8} \to~~ \°C= \dfrac{70-32}{1,8} \to~~ \°C= \dfrac{38}{1,8} \to~~ \°C=21,11111...\\\\\\ \large\boxed{78\°F~ \approx~ 21,11\°C }$
