Partition Line Segments (1 Dimension)

1.Find the Distance between A and B 2.Find the total number of parts (add the ratio or look at the denominator of the fraction) 3.Divide the distance by the number of parts to determine the interval at which each partition will be drawn 4.Draw a partition after the interval found in Step 3 5.Shade (starting at A) the correct amount of parts (first part of the ratio or the numerator of the fraction) 6.The coordinate of the partition will be wherever you end up How to Find the Partition of a Segment
