When two fractions have the same denominator,
the fraction with the larger numerator is larger.
First, identify the fractions represented by the models.
The model on the left is divided into four equal parts, and two parts are shaded.
So, the model represents $\frac{2}{4}$.
The model on the right is divided into four equal parts, and three parts are shaded.
So, the model represents $\frac{3}{4}$.
 

$\frac{2}{4}$  $<$  $\frac{3}{4}$ 
$\frac{2}{4}<\frac{3}{4}$ is the correct comparison because:
• $\frac{2}{4}$ and $\frac{3}{4}$ have the same denominator, and 2 < 3.
• 2 parts of an equallydivided whole is less than 3 parts of an
equallydivided whole of the same size.
• the model of $\frac{2}{4}$ has less area shaded than the model of $\frac{3}{4}$.
