Let two points in one dimensional line segment be , that is number marked on the number line is A(3) and B(15).
Now, Segment AB is to be divided in the ratio of 1:3.
Distance between AB=
Position of Point B on the Number Line - Position of Point A on the number line
=15-3
=12
→Position of Point on the number line which is divided in the ratio of 1:3 will be
→That is at 3 units away from point 3 , that is at Number 6, marked on the number line.
Now Coming to Two dimensional Coordinate system
Consider two points P(6,0) and Q(0,8) in two dimensional coordinate system which is to be divided in the ratio of 1:4.
→Position of Point on the number line which is divided in the ratio of 1:4 will be
Coordinate of the point which is divided in the ratio of 1:3 is equal to=(4.8,1.6)
