Answer:
It is correct
Step-by-step explanation:
El cuarto de mi hermanito hoy esta limpo, generalmente esta un poco sucio.
Translation
My brother's room is clean today, it's usually a bit dirty
Grammatically it is correct, that is, the subject, object and in conjunction with the predicate is correct and the verb conjugation is also correct. But it has a typing error in one of the words: "limpo". This word does not exist and the correct word is "limpio" which means clean.
