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

### Instruction:
 Vijana kumi na sita na wasichana kumi na nne walihudhuria sherehe ya kuzaliwa ya Simon. Watatu kati ya vijana wanne na wasichana 6/7 walileta zawadi. Watu wangapi kati ya wale waliohudhuria hawakuleta zawadi?


### Response:
 Idadi jumla ya vijana na wasichana waliohudhuria ilikuwa 16 + 14 = <<16+14=30>>30.
Idadi ya vijana walioleta zawadi ilikuwa 16 * 3/4 = <<16*3/4=12>>12.
Idadi ya wasichana walioleta zawadi ilikuwa 14 * 6/7 = <<14*6/7=12>>12.
Jumla ya wale walioleta zawadi ilikuwa 12 + 12 = <<12+12=24>>24.
Hivyo, idadi ya wale ambao hawakuleta zawadi ni 30 - 24 = <<30-24=6>>6.
