Depict the division of a circle. Choose which fractions you want visible in the tool.
Press the cursor button in the toolbar to control the tool. Drag a circle with dotted line in the field. Drag a full circle or a fraction into the circle with dotted line. Once a fraction is placed inside of the circle, you can pick it up and move it to another circle. The fraction will disappear if you drop it outside of the circles with dotted line.
Select 'Reset' to clear the field from all fractions and circles with dotted line.
