a fragment is just a part or a 'piece' of a sentence. it could be the subject without a predicate or a predicate without a subject.
a sentence that is not a fragment should have two parts: the subject(the main topic of the sentence) and the predicate(the action or where the verb is at)
A few examples of missing predicates are: My dog. All the people. The wild jungle.
A few examples of missing subjects are: Ran around the yard. Laughed aloud. Is amazing.
put these together and it makes a complete sentence that makes sence: My dog ran around the yard. All the people laughed aloud. The wild jungle is amazing.
All complete sentences should have:a capital letter to start off the sentencea punctuation mark at the enda complete idea and not just an idea fragmenta predicate and subject
If it is not too harsh I would like to point out that maybe you too should look into learning how to write a proper sentence.
