Given:
It is given that
C divides AB so that, AC:AB = 3:8
To find the wrong option among the given options.
Let us take,
AB = [tex]8x[/tex] unit
AC = [tex]3x[/tex] unit
So,
CB = [tex]8x-3x[/tex]
CB = [tex]5x[/tex] unit
So, we can conclude that,
AC: CB: AB = 3:5:8
Hence,
The wrong option is C i.e, Point C is [tex]\frac{3}{5}[/tex] of way from point A to point B.
