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

### Instruction:
 Marbels 36 zimegawanywa kati ya Mario na Manny kwa uwiano wa 4:5. Ikiwa Manny ameamua kumpa ndugu yake marbels 2, Manny ana marbels mangapi sasa?


### Response:
 Marbels zimegawanywa katika sehemu 4 + 5 = <<4+5=9>>9.
Kila sehemu ina marbels 36/9 = <<36/9=4>>4.
Hivyo Manny alikuwa na sehemu 5 x 4 = <<5*4=20>>20 kabla ya kumpa ndugu yake marbels 2.
Baada ya kumpa ndugu yake marbels 2, Manny sasa ana marbels 20 - 2 = <<20-2=18>>18.
