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

### Instruction:
Princeton had a gender reveal party and invited all of his fellow employees to celebrate with him. If the total number of guests were 60, and 2/3 were male guests, how many female guests attended the party?

### Response:
 Idadi ya wanaume katika sherehe ilikuwa 2 wanaume / 3 wageni * 60 wageni = <<2/3*60=40>>40 wanaume.
Ikiwa idadi jumla ya watu katika sherehe ilikuwa 60, basi kulikuwa na 60 wageni - 40 wanaume = <<60-40=20>>20 wanawake.
