Question

Using the image below, find the y value for the point that divides the line segment XY into a ratio of 1:2.

Answer 1

1:2 is not the same as 1/2

1:2 means that the distance is split into 1+2 = 3 equal parts

let C be a point between A and B

Answer 2

let
x = distance from A to C
y = distance from C to B



if C divides AB into a ratio 1:2 then
y = 2*x

ie the distance from C to B is twice as large as the distance from A to C
