Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Johnny ana vifaa 12/(1/3)=<<12/(1/3)=36>>36.
Ikiwa asilimia 50 ya vifaa ni vya rangi nyekundu, basi ana vifaa 36*0.5=<<36*0.5=18>>18 vya rangi nyekundu.
Hivyo, kuna vifaa 36-18-12=<<36-18-12=6>>6 vya rangi manjano katika mkusanyiko wake.
