Let the point (1, 12) divide the line segment joining (5, 6) and (7, 3) in the ratio m : n.
Here the point (1, 12) divides the line segment externally.
If a point divides a line segment joining the points and in the ratio m : n externally, then by section formula,
So here,
Hence 2:3 is the answer.

⭐ Solution ⭐
✏Let the point (1, 12) divide the line segment joining (5, 6) and (7, 3) in the ratio m : n.
✏Here the point (1, 12) divides the line segment externally.
✏ If a point (x,y) divides a line segment joining the point (x1,y1) and (x2,y2) in the ratio of m:n then,
➡ By using section formula:-
=> x = mx2-nx1/m-n
➡ Now,
=> 1 = 7m-5n/m-n
=> 7m - 5n = m - n
=> 7m-m = 5n-n
=> 6m = 4n
=> m/n = 4/6
=> m/n = 2/3
=> m:n = 2:3
✔ Hence, the answer is 2:3
