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

### Instruction:
To let Ruth know how long her fish will live, her father tells her that well-cared fish can live 2 years longer than dogs live. On average, dogs live 4 times as long as hamsters live. And hamsters live an average of 2.5 years. How long can a fish live?

### Response:
 Tukijua kuwa mbwa huishi mara 4 ya umri wa hamster, mbwa huishi 4 * 2.5 = <<4*2.5=10>>10 miaka.
Ikiwa Ruth atatunza samaki, inaweza kuishi miaka 10 + 2 = <<10+2=12>>12.
