A piece of an edge of a circle is called an ARC.
-- One sixth of a circle is a shape that looks like a piece of pie or an ice cream cone. -- It is called a "sector". -- The two straight lines meet at an angle of 60 degrees. -- The length of the curved line is (pi)R/3 . That's about 1.05 times the length of one of the straight lines.
Part of the circumference of a circle is an arc.
Mr. Kevin thinks that estimation can help students get real sense of conversion between fraction and percentage.

If you have the area of the piece and you know how much the piece takes up. For example if you have a piece of a circle and you know it is 1/4 if the circle then you take the area and multiply by 4.

A piece of the circumference of a circle is called an arc A piece of the area of a circle bounded by an arc and two radii is called A sector. A piece of the area of a circle bounded by an arc and a chord is called a segment
There can be no "fraction" without a given basis. What's the fraction based on? What's the whole piece? If we assume the "whole piece" is 360 degrees (which is the entire angle of a circle) then the fraction is n/N = 50/360 = 5/36. But if we assume the whole piece is 180 degrees (which is the entire interior angle of a triangle) then the fraction is n/N = 50/180 = 5/18. Again...we can't give you a fraction if you don't give us a basis...that N in n/N.
One-half of one-third is one-sixth. Using fraction manipulatives would be one way to visually verify that a one-sixth piece would cover half of a one-third piece.

It is a fraction of the length of a piece of string!
You fold the paper into sixths (or eighths, if you want a front and a back cover too) unfold it, cut along the lines you made, and after writing what you need, ou put the papers together in order.
