Question

Fill in the blank with the correct symbol.

$\frac{1}{4}$ __________ $\frac{2}{4}$

Answer

We can create a fraction model to help us solve the problem. The fraction models below show $\frac{1}{}4$ and $\frac{2}{}4$

$\frac{2}{4}$ is greater than $\frac{1}{4}$ , or $\frac{1}{4}$ is less than $\frac{2}{4}$ , because more of the $\frac{2}{4}$ model is filled in.

$\frac{1}{4}<\frac{2}{4}$
