Hi Keisha! Remember, when you need to make a question in Spanish, you need to use those "¿?" at the beggining and at the end. So, Tus preguntas se formulan ( o se escriben) así: 1.¿Quien tiene mas hermanos? 2. ¿Quien tiene menos hermanos? 3. Soy hijo único ( Don't forget the stress mark" ´ " ) And also if you're talking about yourself remember to use the feminine form of the verb. Instead of "unico" you can say "unica". Espero haber ayudado, You're doing good! ¡Que tengas un bonito día! =)
