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

### Instruction:
 Nate anasoma kitabu chenye kurasa 400. Alikamilisha kusoma 20% ya kitabu. Anahitaji kusoma kurasa ngapi ili akamilishe kitabu?


### Response:
 Nate alikuwa amesoma kurasa 400 x 20/100 = <<400*20/100=80>>80.
Hivyo, anahitaji kusoma kurasa 400 - 80 = <<400-80=320>>320 ili akamilishe kitabu.
