Answer:
Each person is receiving 1/16th of the total watermelon
Explanation:
Since the water melon is cut in half let's assume it's whole for the time being. If the watermelon were whole each of the 8 people would receive 1/8th of the melon. Since we know that, and that the current watermelon is cut in half, we can divide 1/8th by 2 to get 1/16th.
