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

### Instruction:
There are 66 goats at a farm and twice as many chickens. If the number of ducks is half of the total of the goats and chickens, and the number of pigs is a third of the number of ducks, how many more goats are there than pigs?

### Response:
 Kuna kuku 66 x 2 = <<66*2=132>>132.
Kuna jumla ya mbuzi na kuku ni 66 + 132 = <<66+132=198>>198.
Kuna bata 198/2 = <<198/2=99>>99.
Kuna nguruwe 99/3 = <<99/3=33>>33.
Kuna mbuzi 66 - 33 = <<66-33=33>>33 zaidi kuliko nguruwe.
