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

### Instruction:
In a forest, there are three anthills. In the first anthill, there are 100 ants, and in each next anthill, there are 20% fewer ants than in the previous one. How many ants are in the third anthill?

### Response:
 Katika mzingiri wa pili, kuna sisimizi 20/100 * 100 = <<20/100*100=20>>20 chini.
Hii inamaanisha kuna sisimizi 100 - 20 = <<100-20=80>>80 katika mzingiri wa pili.
Katika mzingiri wa tatu, kuna sisimizi 20/100 * 80 = <<20/100*80=16>>16 chini ikilinganishwa na mzingiri wa pili.
Hivyo katika mzingiri wa tatu, kuna sisimizi 80 - 16 = <<80-16=64>>64.
