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

### Instruction:
 Kuna wavulana 11 na wasichana 13 darasani. Ikiwa mvulana 1 anaongezwa darasani, asilimia ngapi ya darasa ni wasichana?


### Response:
 Jumla ya wanafunzi darasani ni wavulana 11 + 1 = <<11+1=12>>12.
Hivyo, jumla ya wanafunzi darasani ni wavulana 12 + wasichana 13 = <<12+13=25>>25.
Hivyo, 13/25 x 100% = 52% ya darasa ni wasichana.
