Final answer:
The Inca, Aztec, and Maya all shared the religious practice of offering sacrifices to the gods.
Step-by-step explanation:
The religious practice that the Inca, Aztec, and Maya had in common is offering sacrifices to the gods.
In Aztec culture, ritual sacrifices of humans were conducted throughout the year, often capturing warriors from neighboring states.
The Inca, on the other hand, worshipped the sun god Inti and offered food, clothing, and coca leaves to the gods.
While human sacrifices were rare for the Inca, they did occur in times of extreme emergencies. The Maya also practiced blood sacrifices, including the ripping out of hearts, as seen in their art and depicted in Spanish accounts.
