Answer:- The whole pie will be left after he eats tomorrow is \(\frac{25}{36}\) of the whole pie.
Explanation:-
Pie left from dinner=\(\frac{5}{6}\)
If victor plans to eat 1/6 of the pie that was left,
The whole pie will be left = \(\frac{5}{6}-\frac{1}{6}\ of\ \frac{5}{6}\)
\(=\frac{5}{6}-\frac{1}{6}\times(\frac{5}{6})\\\\=\frac{5}{6}-\frac{5}{36}\\\\=\frac{30-5}{36}=\frac{25}{36}\)
Therefore, the whole pie will be left after he eats tomorrow is \(\frac{25}{36}\) of the whole pie.
