Question

if anyone is good ( or even just okay ) at French then please help me.

Answer 1

I'm pretty okay in French,

What's the question?

Answer 2

I have to change the singular sentences into plural.

1. Voici le crayon
2. C'est une gomme
3. Voilà un livre
4. Voici une affiche
5. Voice le bureau de Mme Gudde
6. Tu aimes le sandwhich?

Answer 3

Ok, I'll just give you some hints

Le and la become les
Un and une become des

Nouns end with -s but some end with -x (endings w/ -au, -l etc) so journal becomes journaux
So voici le crayon, voici les crayons
