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

### Instruction:
A 220-liter barrel has a small leak. It lost 10% of its contents before anyone noticed. How many liters are left in the barrel?

### Response:
 10% ya yaliyomo kwenye pipa ni 10/100 * 220 = <<10/100*220=22>>22 lita.
Pipa lilipoteza lita 22 kabla ya mtu yeyote kugundua, hivyo zimebaki lita 220 - 22 = <<220-22=198>>198 kwenye pipa.
