In Italian, yes/no questions can usually be asked by simply adding a questioning intonation at the end of a sentence.
Il mio or la mia is the typical way to say [my] in Italian. However, the il and la are typically dropped when talking about family members. Thus, we typically say mio fratello rather than il mio fratello (although both are grammatically correct). This is simply idiomatic and must be memorized.
Uno is the Italian word for [One]. When modifying a noun, it shortens to un or una, depending on whether it modifies a masculine or feminine noun.
Due is the Italian word for [Two]. It does not change when modifying a noun.
With the exception of quantifiers like numbers and possessives, adjectives follow the noun that they modify. Therefore we say fratello maggiore or [brother older] to refer to an older brother.
