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

### Instruction:
 Darasani kuna wanafunzi 30, mwalimu anawauliza wanafunzi kuhusu somo lao pendwa. 1/5 ya wanafunzi wanapenda Hisabati, na 1/3 wanapenda Kiingereza. 1/7 ya wanafunzi waliobaki wanapenda Sayansi. Wengine hawana somo pendwa. Wanafunzi wangapi hawana somo pendwa?


### Response:
 30x(1/5)=<<30*1/5=6>>6 wanafunzi wanapenda Hisabati.
30x(1/3)=<<30*1/3=10>>10 wanafunzi wanapenda Kiingereza.
Hivyo 6+10=<<6+10=16>>16 wanafunzi wanapenda Hisabati au Kiingereza.
Kwa hivyo, 30-16=<<30-16=14>>14 wanafunzi hawapendi Hisabati wala Kiingereza.
Kwa kuwa 1/7 ya wanafunzi hawa 14 wanapenda Sayansi, basi 14x(1/7)=<<14*(1/7)=2>>2 wanafunzi wanapenda Sayansi lakini wala Hisabati wala Kiingereza.
Hivyo, 30-16-2=<<30-16-2=12>>12 wanafunzi hawapendi Hisabati, Kiingereza, wala Sayansi.
