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

### Instruction:
Jackson had 20 kilograms of meat. He used 1/4 of the meat to make meatballs and used 3 kilograms of meat to make spring rolls. How many kilograms of meat are left?

### Response:
 Jackson alikuwa na kilo 20 za nyama.
Aliandaa vitumbua vya nyama kwa kutumia 1/4 ya nyama, hivyo kilo 20 * 1/4 = <<20*.25=5>>5 za vitumbua vya nyama.
Aliandaa vitumbua vya majira ya joto kwa kutumia kilo 3 ya nyama.
Alibakiwa na kilo 20 - 5 - 3 = <<20-5-3=12>>12 za nyama.
