Partitives in French.

These articles are used to mention unknown quantities, these should not be confused with an indefinite adjective or pronoun, since in this case the amount is unknown but no clear reference is made to it. in French they have the following:

Du - De: male and singular. De la: female and singular. De 'l: male and female singular (next word begins with vowel or h silent). Des: male and female plural.

Therefore, to properly use a partitive article, the gender and number of the noun it refers to must be identified, once this is recognized, one of the options can be used with the help of the guide above.

Before i start, just letting you know, language teachers are very seriously strict about getting answers from other people, especially online. putting this question out online could be counted as cheating, and having experienced issues where teachers thought i was cheating when i wasn't, it's not fun if you get caught. so i'm going to show you how to do it, but i'm not going to do all of them for you.so the first one has no verb, so you should just be able to change the 'le' to 'les' and just add an s to the end of 'crayon'. that one's kind of easy in that way. voici les crayons.when it has a verb like in #2, you also have to change the verb. the 'c'est' would change to 'ce sont' since that's the plural form of etre. then, since it's not a le/la and it's just one eraser (gomme), it changes to 'des' indicating that there are some crayons instead of all the crayons. then, as with usual plurals, the noun adds an s on the end of it. ce sont des gommes. hopefully that you enough to let you be able to do this work without getting in trouble for them thinking you're cheating. if your teacher or other people in your class are willing to you learn how to do it without doing it for you, that's going to be a much better source of assistance than something like this online.
