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

### Instruction:
 Ali alikuwa na mkusanyiko wa konokono wa baharini. Alianza na konokono 180. Kisha akawapa konokono 40 kwa marafiki zake. Pia akawapa konokono 30 kwa ndugu zake. Ikiwa aliouza nusu ya konokono zilizosalia, alikuwa na konokono wangapi zilizosalia?


### Response:
 Baada ya kutoa konokono 40+30 = <<40+30=70>>70 kwa marafiki na ndugu zake, Ali alibakiwa na konokono 180 - 70 = <<180-70=110>>110.
Ikiwa aliouza nusu ya konokono, aliouza 1/2*110 = 55 konokono.
Ali alibakiwa na 110 - 55 = <<110-55=55>>55 konokono.
