The question on the image asks:

Problem Statement: "Rina membeli 10 meter kain untuk menutup beberapa meja alas yang berukuran sama. Setiap meja menggunakan 2.5 meter kain. Berapakah bilangan alas meja yang diperolehi?"

Translation: "Rina bought 10 meters of fabric to cover several tablecloths of the same size. Each table uses 2.5 meters of fabric. How many tablecloths can be made?"

Solution: To find out how many tablecloths can be made, you divide the total amount of fabric by the fabric needed per tablecloth:

$\text{Number of tablecloths} = \frac{\text{Total fabric}}{\text{Fabric per tablecloth}} = \frac{10}{2.5}$

Calculating this:

$\frac{10}{2.5} = 4$

Answer: Rina can make 4 tablecloths.
