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

### Instruction:
Julia had to make 6 cakes for the party. Each cake takes 12 minutes to mix and needs 9 more minutes to bake than mix. Then it takes 6 more minutes to cool and decorate than to bake. How many hours will it take to make all 6 cakes?

### Response:
 Inachukua dakika 12 + 9 =<<12+9=21>>21 kuchoma kila keki.
Inachukua dakika 21 + 6 = <<21+6=27>>27 kupoa na kupamba kila keki.
Hivyo, inachukua jumla ya dakika 12 + 21 + 27 = <<12+21+27=60>>60 kutengeneza keki moja.
Hivyo, inachukua 60/60 = <<60/60=1>>1 saa kuchoma keki moja.
Hivyo, itachukua 1 x 6 = <<6=6>>6 masaa kuchoma keki zote 6.
