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

### Instruction:
Kiarra is twice as old as Bea. Job is 3 times older than Bea. Figaro is 7 years older than Job. Harry is half as old as Figaro. If Kiarra is 30, how old is Harry?

### Response:
 Kiarra ana umri wa 30, mara mbili ya umri wa Bea, hivyo Bea ana umri wa 30/2 = <<30/2=15>>15 miaka
Job ana umri wa mara tatu ya Bea, hivyo ana umri wa 15*3 = <<3*15=45>>45 miaka
Figaro ana umri wa miaka 7 zaidi ya Job, hivyo ana umri wa 45+7 = 52 miaka
Harry ana umri wa nusu ya umri wa Figaro, hivyo ana umri wa 52/2 = <<52/2=26>>26 miaka
