### Instruction:
 Bundi mmoja wa shamba anatoa sauti 5 kwa dakika. Ikiwa sauti 5 chini ya sauti 20 kwa dakika zinasikika zikitoka kwenye banda, bundi wangapi wa shamba wanatoa sauti hii?


### Response:
 Sauti 5 chini ya sauti 20 kwa dakika ni 20-5=<<20-5=15>>15 sauti kwa dakika.
Ikiwa bundi mmoja wa shamba anatoa sauti 5 kwa dakika, basi sauti 15 kwa dakika zinatoka kwa bundi 15/5=<<15/5=3>>3 wa shamba.
