## Section or Ratio Tutorial

##### Section or Ratio Definition

Ratio formula or section formula is used to find the coordinates of a point P which divides the segment joining the points A and B internally or externally in the ratio m n.

##### Section or Ratio Example

###### Case 1 :

Find the coordinates of the point which divides the line joining the points (2, 3), (5, 6) internally in the ratio 21.
x_{1} = 2,y_{1} = 3 and
x_{2} = 5,y_{2} = 6
m = 2,n = 1
Substitute in the formula as

###### Case 2 :

Find the coordinates of the point which divides the line joining the points (2, 1), (3, 5) internally in the ratio 25.
x_{1} = 2,y_{1} = 1 and
x_{2} = 3,y_{2} = 5
m = 2,n = 5
Substitute in the formula as

The above example will clearly illustrates how to calculate the Coordinates of Point Externally/Internally using Section or Ratio formula manually.
