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

### Instruction:
Samuel swept the porch and cleared nine-tenths of the dust particles from it. As he walked across the porch afterward, his shoes left 223 dust particles behind. How many dust particles were on the porch before Samuel swept if there were 331 after he walked across it?

### Response:
 Kabla Samuel hajapita kwenye veranda, kulikuwa na chembechembe 331 - 223 = 108 za vumbi.
Hizo 108 zilikuwa 1/10 ya idadi ya awali, hivyo kulikuwa na chembechembe 108 * 10 = <<108*10=1080>>1080 za vumbi kwenye veranda kabla Samuel hajasafisha.
