CREATE TABLE table_name_61 (sinclair_coefficient INT, sinclair_total VARCHAR, weight_class__kg_ VARCHAR)

What is the average sinclair coefficient with a Sinclair Total of 477.2772023, and a Weight Class (kg) larger than 105?
SELECT AVG(sinclair_coefficient) FROM table_name_61 WHERE sinclair_total = 477.2772023 AND weight_class__kg_ > 105
SELECT AVG("sinclair_coefficient") FROM "table_name_61" WHERE "sinclair_total" = 477.2772023 AND "weight_class__kg_" > 105
