You could baby-talk your way through this one . . .
Find the point that divides the line segment into the ratio
given:
We want a point which is the distance from to
. . . . . . . . . . . . . . . .
. .
To go from to , we'd move:
To go three-fourths the distance, we'd move:
Hence, is: .
Of course, this is basically Earboth's solution.
