La temperatura de un congelador bajó de 3 °C a −9 °C en 3 horas. Si la temperatura del congelador bajó en la misma cantidad de g
kolbaska11 [484]

Usando proporciones, se encuentra que al final de la primera hora, el congelador tenía una temperatura de -1ºC.

  • Este problema se resuelve por proporciones.
  • En 3 horas, la temperatura bajó 12ºC, puesto que 3 - (-9) = 12.

La temperatura del congelador bajó en la <u>misma cantidad de grados cada hora</u>, o sea, en la primera hora, la cantidad que bajo es:

\frac{12}{3} = 4

4ºC bajo a 3ºC es:

3 - 4 = -1

O sea, al final de la primera hora, el congelador tenía una temperatura de -1ºC.
