"You eat fruit and cheese."
Translation:I spiser frugter og ost.
Fruit in English is both singular and plural, while in Danish, frugt is only singular. When you're talking about more than one piece of fruit, you always have to use the plural form, frugter.
"You" = Both "du" and "I". Du is used when speaking to one person, I is used when speaking to more than one person
Fruit is singular and not plural, therefor the translation should be: "frugt" and not "frugter".
