Answer:
3 1/2 is between 3 and 4 in the MIDDLE. 3/12 would be between 3 and 3 1/10
There are 13 spades in a standard deck of cards, so if the first one is a spade, there are 12 spades left.
So the chances of getting another one would be 12/52 because there are 52 cards in a standard deck of cards.
Reduced, your answer is 3/13
