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

### Instruction:
 Oliver alikuwa na stika 135. Alitumia 1/3 ya stika zake, akampa rafiki yake 2/5 ya zilizobaki, na akabaki na stika zilizosalia. Alibaki na stika ngapi?


### Response:
 Oliver alitumia 1/3 x 135 = <<1/3*135=45>>45 stika.
Hivyo kulikuwa na stika 135 - 45 = <<135-45=90>>90 zilizobaki.
Rafiki yake alipokea 2/5 x 90 = <<2/5*90=36>>36 stika.
Hivyo, Oliver alibaki na stika 90 - 36 = <<90-36=54>>54.
