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

### Instruction:
One US cup equals 250ml. Brian is making lasagna for himself, his wife, his two kids, his parents, and his wife's parents. The recipe requires 1/2 a cup of milk per serving. How many 1L cartons of milk does Brian need to buy if each person is expected to eat 2 servings?

### Response:
 Kikombe kimoja cha Marekani ni 250 ml, hivyo 1/2 kikombe cha Marekani ni 125 ml.
Kuna watu 4 katika familia ya Brian, na watu 2 katika familia ya mkewe.
Kila mtu anatarajiwa kula sehemu 2, hivyo kuna (4+2)*2=<<(4+2)*2=12>>12 sehemu.
Kila sehemu inahitaji 125 ml ya maziwa, hivyo jumla ya maziwa yanayohitajika ni 125*12=<<125*12=1500>>1500 ml.
Kuna 1000 ml katika pakiti ya 1L, hivyo Brian anahitaji 1500/1000=<<1500/1000=1.5>>1.5 pakiti za maziwa.
