1. which area model matches the problem? $\frac{5}{10} div \frac{1}{4}$

(there are some audio buttons and area model options with green and white rectangles)

Explanation:

Step1: Simplify the dividend

$\frac{5}{10} = \frac{1}{2}$

Step2: Rewrite division as multiplication

$\frac{1}{2} \div \frac{1}{4} = \frac{1}{2} \times 4$

Step3: Calculate the result

$\frac{1}{2} \times 4 = 2$

Step4: Match to area model

The third model shows 2 full rows of 10 equal green parts, representing the value 2.

Answer:

The third area model (the one with two full rows of all green rectangles) matches the problem.
