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

### Instruction:
 Shule ya Upili ya Chalktown ilifanya prom yao mwishoni mwa wiki iliyopita. Kulikuwa na wanafunzi 123 waliohudhuria. Ikiwa wanafunzi 3 walihudhuria peke yao, wapenzi wangapi walikuja kwenye prom?


### Response:
 Kulikuwa na wanafunzi 123 - 3 waliohudhuria peke yao = <<123-3=120>>120 wanafunzi walio na wapenzi.
120 wanafunzi / 2 kwa kila penzi = <<120/2=60>>60 wapenzi.
