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

### Instruction:
 John anakwea ngazi za ghorofa 9. Kila ghorofa ni futi 10. Ikiwa kila hatua ni inchi 18, anapanda hatua ngapi?


### Response:
 Anahitaji kupanda futi 9*10=<<9*10=90>>90
Hii inamaanisha anahitaji kupanda inchi 90*12=<<90*12=1080>>1080
Hii inamaanisha anahitaji kupanda hatua 1080/18=<<1080/18=60>>60
