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

### Instruction:
There are 5 houses on a street, and each of the first four houses has 3 gnomes in the garden. If there are a total of 20 gnomes on the street, how many gnomes does the fifth house have?

### Response:
 Katika nyumba nne za kwanza, kuna jumla ya wachawi 3 kwa nyumba * nyumba 4 = <<3*4=12>>12 wachawi.
Kwa hiyo, nyumba ya tano ilikuwa na jumla ya wachawi 20 - wachawi 12 = <<20-12=8>>8.
