One number-line whole runs from 0 to 1. Six evenly spaced boundary marks label 0,1/5,2/5,3/5,4/5,1. Five equal gaps are the parts. A marker lies on 3/5, three equal gaps from 0 and two from 1. Relation 3/5+2/5=1 whole. Colour supplies no extra information. Units are mathematical intervals, not real centimetres or a calibrated tool. Describe or create a different own line using your usual communication; record actual drawing/operation/directing separately. Original CC BY 4.0.
