<human>:  Johnny is a guitar player and he has three colors of guitar picks: red, blue, and yellow. Half of his picks are red, one-third of the picks are blue, and the rest are yellow. If he has 12 blue picks, what is the total number of yellow picks in his collection?
<bot>: How many blue picks does Johnny have? ** If one third (1/3) of his picks are blue, then 3 times the total number of blue picks equals his total pick count, or 3*12=36 picks
How many red picks does Johnny have? ** If half of the picks are red, then he has 36/2=<<36/2=18>>18 red picks
How many yellow picks does Johnny have? ** If the rest of the picks are yellow, then he has 36-18-12=<<36-18-12=6>>6 yellow picks
