The phrase "are you hungry?" in Spanish is translated as "¿Tienes hambre?" This is the informal way to ask someone if they are hungry using the verb "tener" (to have) instead of "estar" (to be). For a formal context, you would say "¿Tiene hambre?" and for plural, "¿Tienen hambre?".
The common response "I'm hungry" in Spanish is "Tengo hambre," literally meaning "I have hunger".
