2-10.

Mario ordered a pizza for dinner. When it arrived, Mario quickly ate $\frac { 1 } { 8 }$ of the pizza. While Mario was getting napkins, his pet poodle ate $\frac { 1 } { 3 }$ of the pizza. Homework Help ✎

1. Draw a model of the pizza that shows the portion that has been eaten.

Then, find what size pieces could make up one third of the pizza or one eighth of the pizza. You can do this by finding the lowest common multiple of $8$ and $3$, the denominators of the two fractions.
The LCM of $3$ and $8$ is $24$, so there should be $24$ pieces. Indicate which ones were eaten, and which ones were not.
