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

### Instruction:
Mr. Lu owns a computer store. For last month, half of their sales are laptops, one-third are netbooks, and the rest are desktop computers. If Mr. Lu's store was able to sell a total of 72 computers, how many of them are desktop computers?

### Response:
 Kulikuwa na kompyuta 72/2 = <<72/2=36>>36 za mkononi zilizouzwa.
Kulikuwa na kompyuta 72/3 = <<72/3=24>>24 za mtandao zilizouzwa.
Hivyo, kulikuwa na jumla ya kompyuta 36 + 24 = <<36+24=60>>60 za mkononi na za mtandao zilizouzwa.
Hivyo, kompyuta 72 - 60 = <<72-60=12>>12 za mezani zilizouzwa mwezi uliopita.
