1. los primeros (1) chicos
2. el tercer (3) libro
3. la sexta (6) planta
4. las á (10) ediciones

Explanation:

To find the Spanish ordinal number for 10 (plural, feminine - since "ediciones" is feminine plural), the ordinal number for 10 is "décimo" in singular, but for plural feminine, we use "décimas". Wait, no, let's correct: The ordinal number for 10 in feminine plural (since "las" and "ediciones" are feminine plural) is "décimas"? Wait, no, the base is "décimo" (masculine singular), "décima" (feminine singular), "décimos" (masculine plural), "décimas" (feminine plural). Wait, but the digit is 10, so the ordinal is "décima" for singular feminine, "décimas" for plural feminine. Since "ediciones" is plural and feminine, we need "décimas"? Wait, no, let's check the structure. The first three examples: 1 (primeros - masculine plural), 3 (tercer - masculine singular), 6 (sexta - feminine singular). Now 4: "las" (feminine plural) and "ediciones" (feminine plural), digit 10. So the ordinal number for 10 in feminine plural is "décimas"? Wait, no, "primeros" is masculine plural for 1, "tercer" is masculine singular for 3, "sexta" is feminine singular for 6. So for 10, feminine plural (las, ediciones), the ordinal is "décimas"? Wait, no, "décimo" is the ordinal for 10 (masculine singular), "décima" (feminine singular), "décimos" (masculine plural), "décimas" (feminine plural). So since "las" and "ediciones" are feminine plural, we use "décimas". Wait, but let's confirm: 1 (uno) → primero (masculine singular), primeros (masculine plural); 3 (tres) → tercer (masculine singular, note the spelling: tercer instead of tercero? Wait, "tercero" is the masculine singular, but before a noun, it's "tercer" (like "el tercer libro" instead of "el tercero libro"). Similarly, 6 (seis) → sexta (feminine singular, "la sexta planta"). For 10 (diez), the ordinal is "décimo" (masculine singular), "décima" (feminine singular), "décimos" (masculine plural), "décimas" (feminine plural). So since "las" and "ediciones" are feminine plural, we need "décimas". Wait, but let's check the form. The first example: "primeros" (masculine plural, 1), second: "tercer" (masculine singular, 3), third: "sexta" (feminine singular, 6). So for 4, "las" (feminine plural) and "ediciones" (feminine plural), digit 10, so the ordinal is "décimas". Wait, but maybe I made a mistake. Wait, "diez" → ordinal is "décimo". So "las décimas ediciones" (the tenth editions, but plural). So the correct ordinal is "décimas".

Answer:

décimas
