Identify the numeric order of these fractions and mixed numbers from smallest to largest: 1 3/6 2 * 3/pi 7/0 1 7/8

The fractions and mixed numbers, in numeric order from smallest to largest, are:

7/0 (undefined, as division by zero is not possible)
1 3/6 (which simplifies to 1/2)
2 * 3/pi (approximately 1.9099)
1 7/8 (which can be written as 15/8)

Therefore, the correct order is: 7/0, 1/2, approximately 1.9099, 15/8.
