CREATE TABLE table_70060 ("Rank" FLOAT, "Circuit" CLOB, "Headquarters" CLOB, "Screens" FLOAT, "Sites" FLOAT)

what is the number of sites when the number of screens is 687 and rank is more than 7?
SELECT AVG("Sites") FROM table_70060 WHERE "Screens" = '687' AND "Rank" > '7'
SELECT AVG("Sites") FROM "table_70060" WHERE "Rank" > '7' AND "Screens" = '687'
