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

### Instruction:
 Bi. Fredrickson ana kuku 80 ambapo 1/4 ni jogoo na wengine ni kuku. Ni kuku wangapi ambao Bw. Fredrickson ana ambao hawatoi mayai?


### Response:
 1/4 ya kuku 80 ni jogoo, ambayo inamaanisha kuna 80 x (1/4) = <<80*(1/4)=20>>20 jogoo.
Idadi ya kuku ni 80 - 20 = <<80-20=60>>60.
Ni kuku 60 x (3/4) = <<60*(3/4)=45>>45 tu ndio wanaotoa mayai.
Kuna kuku 60 - 45 = <<60-45=15>>15 ambao hawatoi mayai.
Bw. Fredrickson ana jumla ya kuku 20 + 15 = <<20+15=35>>35 ambao hawatoi mayai.
