In 1 / 3 × 12, 12 × 1 / 3, 1 / 3 × 5 / 7, 4 / 3 × 0, 5 / 2 × 1, 1 / 3 × 1 / 2 In 1 / 3 × 12,12 × 1 / 3, 1 / 3 × 5 / 7, 4 / 3 × 0, 5 / 2 × 1, 1 / 3 × 1 / 2, the product of the maximum and the first factor () is equal to that of the first factor () and less than that of the first factor () is equal to that of the product ()

In 1 / 3 × 12, 12 × 1 / 3, 1 / 3 × 5 / 7, 4 / 3 × 0, 5 / 2 × 1, 1 / 3 × 1 / 2 In 1 / 3 × 12,12 × 1 / 3, 1 / 3 × 5 / 7, 4 / 3 × 0, 5 / 2 × 1, 1 / 3 × 1 / 2, the product of the maximum and the first factor () is equal to that of the first factor () and less than that of the first factor () is equal to that of the product ()

In 1 / 3 × 12, 12 × 1 / 3, 1 / 3 × 5 / 7, 4 / 3 × 0, 5 / 2 × 1, 1 / 3 × 1 / 2, the product of the maximum and the first factor is (1 / 3 × 12,), and the product of the maximum and the first factor is (5 / 2 × 1), Those whose product is less than the first factor are (12 × 1 / 3, 1 / 3 × 5 / 7, 1 / 3 × 1 / 2, 4 / 3 × 0), and those whose product is equal to 0 are (4 / 3 × 0)
Five points for the time being, and 20 points will be added if the answer is correct. Thank you (*^__ ^*)
