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

### Instruction:
 Kulikuwa na maballoni 672 ambayo yalikuwa ya rangi ya kijani, buluu, njano, au nyekundu. Yaligawanywa katika makundi sawa na kisha Anya akachukua nusu ya maballoni ya njano nyumbani. Anya alichukua maballoni mangapi nyumbani?


### Response:
 Kulikuwa na maballoni 672/4 = <<672/4=168>>168 katika kila rangi.
Anya alichukua nusu ya maballoni ya njano, ambayo inamaanisha 168 * (1/2) = 84 maballoni.
