1.Draw a ray PX making acute angle with PQ line of 7cm

2.Locate 7 points such that distance between each point is equal named P_{1},P_{2},P_{3},P_{4},P_{5},P_{6},P_{7}

3.Join QP7

4.Through point P3 draw a line parallel to line QP7 at P3 intersecting PQ at pinot A then PA : AQ is 3 : 4

Ratio 3 : 4 = 3 + 4 = 7

The point A divides PQ

∴ PA : AQ = 3 : 4
