{"North America": {"Number of Manufacturing Facilities": 44, "Food Care Manufacturing Facilities": 10, "Product Care Manufacturing Facilities": 37}, "Europe, Middle East and Africa (\"EMEA\")": {"Number of Manufacturing Facilities": 29, "Food Care Manufacturing Facilities": 11, "Product Care Manufacturing Facilities": 24}, "South America": {"Number of Manufacturing Facilities": 6, "Food Care Manufacturing Facilities": 6, "Product Care Manufacturing Facilities": 1}, "Asia, Australia and New Zealand (\"APAC\")": {"Number of Manufacturing Facilities": 28, "Food Care Manufacturing Facilities": 9, "Product Care Manufacturing Facilities": 24}, "Total": {"Number of Manufacturing Facilities": 107, "Food Care Manufacturing Facilities": 36, "Product Care Manufacturing Facilities": 86}}
south_america_facilities = df["South America"]["Number of Manufacturing Facilities"]
total_facilities = df["Total"]["Number of Manufacturing Facilities"]
answer = south_america_facilities / total_facilities * 100.0
