{"Net revenues by platform: -- Console": {"2019": 1920, "2018": 2538, "Increase/ (decrease)": -618, "% Change": -24}, "Net revenues by platform: -- PC": {"2019": 1718, "2018": 2180, "Increase/ (decrease)": -462, "% Change": -21}, "Net revenues by platform: -- Mobile and ancillary (1)": {"2019": 2203, "2018": 2175, "Increase/ (decrease)": 28, "% Change": 1}, "Net revenues by platform: -- Other (2)": {"2019": 648, "2018": 607, "Increase/ (decrease)": 41, "% Change": 7}, "Net revenues by platform: -- Total consolidated net revenues": {"2019": 6489, "2018": 7500, "Increase/ (decrease)": -1011, "% Change": -13}}
net_revenue_pc_2019 = df["Net revenues by platform: -- PC"]["2019"]
net_revenue_total_2019 = df["Net revenues by platform: -- Total consolidated net revenues"]["2019"]
answer = (net_revenue_pc_2019 / net_revenue_total_2019) * 100.0
