I would help him with food or clothes.

I would contact a social organization for help.

I would talk to him to understand his situation.

I would walk away and do nothing.

I would give him some money for immediate help.

I would inform him about a shelter or child care center.

If i have an extra food i will give him, if i don't have i'll have no choice but to pass by and just wish the next person who come have the means to help him
