Answer:

El período paleolítico corresponde a $\frac{332}{333}$ de la época prehistórica.

Step-by-step explanation:

En primer lugar, se determina la extensión de tiempo, medida en años, tanto de la época prehistórica como el período paleolítico: (Nótese que el signo negativo significa a.C.)

Época Prehistórica

$\Delta T = -2500-(-2500000)$

$\Delta T = 2497500\,years$

Período Paleolítico

$\Delta t = -10000 - (-2500000)$

$\Delta t = 2490000\,years$

La fracción de la época prehistórica que corresponde al período paleolítico es:

$r = \frac{\Delta t}{\Delta T}$

$r = \frac{2490000\,years}{2497500\,years}$

$r = \frac{332}{333}$

El período paleolítico corresponde a $\frac{332}{333}$ de la época prehistórica.
