Question 744456
The ratio does not work.

{{{1/2+1/3+1/4=6/12+4/12+3/12=13/12}}}


Better is you have the ratio of 6 to 4 to 3, so the 169 apples can be cut into 13 equal parts.  


Biff gets {{{(6/13)*169=6*13}}}
Bertha gets {{{(4/13)*169=4*13}}}
Bartholomew gets {{{(3/13)*169=3*13}}}


Those should sum to 169.
