II. Transforma cada expresión al singular o al plural,según corresponda. a) __ / las barajas de tarot e) __ / los panes de queso b) el maquillaje de moda / __ f) el área de finanzas / __ C) __ /los árboles de Navidad g) __ / las hamburguesas de pollo d) la hora de marchar / __ h) el ama de casa / __

## Step 1<br />The problem involves transforming singular expressions into plural and vice versa. The rules of Spanish grammar are used to make these transformations.<br /><br />## Step 2<br />For example, in Spanish, to make a noun plural, we generally add "-s" to the end of the word if it ends in a vowel, or "-es" if it ends in a consonant.<br /><br />## Step 3<br />However, there are exceptions to this rule. For example, the word "hora" becomes "horas" when it is plural, not by adding "-s" but by changing the "a" to "as".<br /><br />## Step 4<br />Similarly, the word "árbol" becomes "árboles" when it is plural, not by adding "-s" but by changing the "l" to "lves".<br /><br />## Step 5<br />The problem also involves transforming expressions that are not nouns but rather phrases. For example, "el maquillaje de moda" becomes "el maquillaje de moda" when it is plural, not by adding "-s" but by changing the "a" to "as".
