Salam alaykum wa rahmatullah wa barakatuhu,
dear sister depending on who they are you may choose different approaches, you need to understand what tye of person they are because some people may need to be scared of the punishment, others need the hope of the reward, others need both and others none for they may need something related to what they can see so you could let them see how important it is for the people around them to pray. Try to speak to them directly and seriously, if they're adult people tell them that you want them to be good examples to you and you want to teach your children what THEY must teach you, and tell them of how happy and please your heart feels when you seee the praying, and when you pray together and tell them that no matter what type of stress or difficulty we or they face in the end we're all going to die and what we want to leave behind in the world is a good legacy and good teaching and good examples and what we want to look forward in the akhira is a good eternal life in bliss and mercy of Allah. if you can be more specific i could try to write some more in sha allah
wa salam
