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

### Instruction:
Kara mixes cups of sugar and water in the ratio of 1:2 to make one liter of lemonade. Calculate the total number of cups of sugar used if she used 84 cups to make lemonade.

### Response:
 Uwiano jumla wa vikombe vya sukari na maji vinavyohitajika kutengeneza limau ni 1+2 = <<1+2=3>>3
Kutengeneza lita moja ya limau, Kara anachanganya vikombe 3 kwa uwiano wa 1:2.
Kiwango kinachowakilisha vikombe vya sukari katika mchanganyiko ni 1/3, na kwa kuwa alitumia vikombe 84 wakati wa kutengeneza limau, alitumia vikombe 1/3*84 = <<84*1/3=28>>28 vya sukari.
