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

### Instruction:
Tom bought 10 packages of miniature racing cars. Each package contains five cars. He gave each of his two nephews 1/5 of the cars. How many miniature racing cars are left with Tom?

### Response:
 Tom alikuwa na magari madogo ya mbio 10 x 5 = <<10*5=50>>50.
Tom alitoa magari madogo ya mbio 10 kwa kila mpwa wake.
Jumla, alitoa magari 10 x 2 = <<10*2=20>>20 kwa wawili wake.
Hivyo, amebakiwa na magari madogo ya mbio 50 - 20 = <<50-20=30>>30.
