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

### Instruction:
Joseph had 16 baseball cards. He gave 3/8 of the cards to his brother and 2 cards to his brother. What percentage of the cards is left to Joseph?

### Response:
 Joseph alitoa 16 kadi * 3/8 = <<16*3/8=6>>6 kadi kwa ndugu yake.
Alitoa jumla ya kadi 6 + 2 = <<6+2=8>>8.
Joseph ana kadi 16 - 8 = <<16-8=8>>8 zilizobaki.
Hii ni 8 kadi / 16 kadi = 50% ya kadi zake.
