The Serbian word "нашим" means "to/for/by/with our" (dative/instrumental plural form of "наш," meaning "our").
The word 'нашим' is used here as a dative masculine plural form meaning 'our', matching the dative case required by the preposition 'са' ('with').

We are going on a picnic with our friends.
The word 'нашим' functions as a dative masculine plural form, associated with 'предлога' ('proposals') to indicate to whom the proposals are directed.
Ово је један од предлога за побољшање нашим пројектима.
This is one of the proposals for improving our projects.
The word 'нашим' is dative masculine plural, used because it modifies 'идејама' ('ideas') in the dative case due to the verb 'помоћи' ('help').
