ANSWER
[tex]\frac{1}{6}\text{ of the pizza is left.}[/tex]EXPLANATION
Janet ate 2/3 of the pizza and pat ate 1/6 of the pizza.
To find how much of the pizza is left, add up the fractions that have been eaten and subtract that from a whole.
That is:
[tex]\begin{gathered} 1-(\frac{2}{3}+\frac{1}{6}) \\ 1-(\frac{5}{6}) \\ \frac{1}{6} \end{gathered}[/tex]That is the amount of the pizza that is left.
