CREATE TABLE table_7208 ("Objects" TEXT, "Date" TEXT, "SiO 2" FLOAT, "Al 2 O 3" FLOAT, "Fe 2 O 3" FLOAT, "K 2 O" FLOAT, "Na 2 O" FLOAT)

What is the highest SiO 2, when K 2 O is greater than 0.16, when Fe 2 O 3 is greater than 0.16, and when Na 2 O is less than 7.53?
SELECT MAX("SiO 2") FROM table_7208 WHERE "K 2 O" > '0.16' AND "Fe 2 O 3" > '0.16' AND "Na 2 O" < '7.53'
SELECT MAX("SiO 2") FROM "table_7208" WHERE "Fe 2 O 3" > '0.16' AND "K 2 O" > '0.16' AND "Na 2 O" < '7.53'
