Modeling: Draw models to represents frac{3}{4} and 2frac{3}{5}.

Step 1
The model for the fraction ${\displaystyle \frac{3}{4}}$ is shown below. You can think a circular pizza.
Now divide it 4 equal slices. Then ${\displaystyle \frac{3}{4}}$ represent three pizza slice.

Step 2
The model for the fraction ${\displaystyle 2\frac{3}{5}}$. First note that
${\displaystyle 2\frac{3}{5}=2\times 5+\frac{3}{5}=\frac{13}{5}}$
You can think you have three circular pizzas. Now divide it each pizza by 5 equal slices. Then you have total ${\displaystyle 5\times 3=15}$ slices. Then ${\displaystyle 2\frac{3}{5}}$ represent total 13 pizza slices. That meas, two complete pizza and three slices from the third pizza.
