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

### Instruction:
There are 20 students in a class. Only one-fourth of the students stayed in the classroom while the rest went to the playground. Of those who went to the playground, one-third are boys. How many girls are there on the playground from this class?

### Response:
 Kati ya wanafunzi 20, 20 x 1/4 = <<20*1/4=5>>5 waliobaki darasani.
Wakati 20 - 5 = <<20-5=15>>15 walienda uwanjani.
Kati ya hao 15, 15 x 1/3 = <<15*1/3=5>>5 ni wavulana.
Hivyo, kuna 5 - 5 = <<5-5=0>>0 wavulana darasani.
Hivyo, kuna 15 - 5 = <<15-5=10>>10 wasichana uwanjani kutoka darasani hii.
