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

### Instruction:
 Kwenye bafu ya familia ya Anne, kuna mafuta ya meno yenye gramu 105. Baba yake Anne anatumia gramu 3 kila anaposafisha meno, mama yake anatumia gramu 2, Anne na kaka yake wanatumia gramu 1 kila mmoja. Kila mwanafamilia anasafisha meno mara tatu kwa siku. Itachukua siku ngapi kwa mafuta ya meno kuisha?


### Response:
 Anne na kaka yake wanatumia gramu 1 + 1 = <<1+1=2>>2.
Wanafamilia wote wanne wanatumia gramu 3 + 2 + 2 = <<3+2+2=7>>7 gramu/safisha.
Kila siku, familia inatumia gramu 7/safisha * 3 safisha/siku = <<7*3=21>>21 gramu.
Mafuta ya meno yatachukua gramu 105 / 21 gramu/siku = <<105/21=5>>5 siku.
