Answer:
C. less than 1/2
Explanation:
The family made a total of 2 pizzas.
They ate 1 and 1/8 pizza before and 1/2 after the movie.
The total proportion of pizza eaten from the second one will be:
[tex]\begin{gathered} =\frac{1}{8}+\frac{1}{2} \\ =\frac{1}{8}+\frac{4}{8} \\ =\frac{5}{8} \end{gathered}[/tex]Therefore, the amount of pizza left will be:
[tex]\begin{gathered} =1-\frac{5}{8} \\ =\frac{3}{8} \\ =0.375 \end{gathered}[/tex]Since 0.375 is closer to 1/2 than 1, a reasonable estimate for the amount of pizza left is less than 1/2.
