(x,y)=(x1+k(x2-x1),y1+k(y2-y1))
k is determined by writing the numerator over the sum of the numerator and the denominator of the original ratio.
k=3/(3+7)=3/10.
Point A is located at (5, 10) and point B is located at (20, 25).
(x,y)=(5+(3/10)*(20-5),10+(3/10)*(25-10))
(x,y)= (9.5,14.5)
The answer would be
(9 1/2, 14 1/2)
