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

### Instruction:
 Mti mrefu una urefu wa mita 20. Ulikatwa kwa njia ambayo uliacha kuwa mrefu kwa 30%. Urefu wa mti ni upi?


### Response:
 Sehemu iliyokatwa ya mti ni mita 20 * 30/100 = <<20*30/100=6>>6.
Hivyo mti umebaki na urefu wa mita 20 - 6 = <<20-6=14>>14.
