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

### Instruction:
 Bob, Tom, Sally, na Jerry walikula chakula cha jioni katika pizzeria yao pendwa. Waliamua kugawana pizza 2. Bob alikula nusu ya pizza pekee yake. Tom alikula theluthi moja ya pizza. Sally hakuwa na njaa sana na alikula sita ya pizza, na Jerry alikula robo ya pizza. Ikiwa kila pizza imekatwa vipande 12, vipande vingapi vilibaki?


### Response:
 Kila pizza ina vipande 12. Bob alikula vipande 12 / 2 = <<12/2=6>>6.
Tom alikula theluthi moja, au vipande 12 / 3 = <<12/3=4>>4.
Sally alikula sita, au vipande 12 / 6 = <<12/6=2>>2.
Jerry alikula robo, au vipande 12 / 4 = <<12/4=3>>3.
Jumla, walikula vipande 6 + 4 + 2 + 3 = <<6+4+2+3=15>>15.
Walioagiza pizza 2, hivyo jumla ya vipande vilivyosalia ni vipande 12 kwa pizza * 2 pizza = <<2*12=24>>24 vipande.
Walibakiwa na vipande 24 - 15 = <<24-15=9>>9 vipande.
