Answer:
[tex](1)(\frac{142}{168})[/tex] is the excess eaten by Fido.
Step-by-step explanation:
The eaten pie ratios are as follows, Andy ate 4/7 of his pie, Barry ate 7/12 of his pie, and Craig ate 5/8 of his pie.
The winner of the contest is Craig, who ate ([tex]\frac{5}{8}[/tex]) of his pie, which is 62.5 %.
The remaining parts of pie are given by,
= [tex](1-\frac{4}{7})+(1-\frac{7}{12})+(1-\frac{5}{8})[/tex]
=[tex]\frac{3}{7} + \frac{5}{12} + \frac{3}{8}[/tex]
= [tex]\frac{205}{168}[/tex]
This was the amount eaten by dog Fido.
The excess eaten by Fido than winner is,
=[tex]\frac{205}{168} - \frac{5}{8}[/tex]
=[tex]\frac{310}{168}[/tex]
=[tex](1)(\frac{142}{168})[/tex]
