The circumference, �, of a circle is �=2��, where � is the radius of the circle. For the given circle with a radius of 1, the circumference is �=2(�)(1), or �=2�.

To find what fraction of the circumference the length of ��⌢ is, divide the length of the arc by the circumference, which gives �3÷2�. This division can be represented by �3*12�=16.

The fraction 16 can also be rewritten as 0.166 or 0.167.

The final answer is 16, 0.166, or 0.167
