Question

mi hermano mi amigo del banco del muchacho

Answer 1

For articles and personal pronouns, it's a matter of slight memorization. El becomes Los. La becomes Las. Mi becomes Mis. Su becomes Sus, and so on. You also add either an -s or -es to the end of the object. El oso would be Los osos. Mi hermano would become mis hermanos, etcetera.
