if 3/4 where made by family and 1/4 where made my friends then there isnt anymore to be made that is 4/4 lol so i guess that you made none i do not know i am trying to help but its a little confusing hope i helped though
If 3/4 of the cards (300) were made by your family and 1/4 of the cards (100) were made by your friends then that would leave us with having 0 cards left. (300 + 100 = 400) So, you made 0 cards.
