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 90 students who have lunch during period 5. Today, two-thirds of the students sat in the cafeteria, while the remainder sat at the covered picnic tables outside. But some yellow-jackets were attracted to their food, and so one-third of the students outside jumped up and ran inside to the cafeteria, while 3 of the students in the cafeteria went outside to see what all the fuss was about. How many students are now in the cafeteria?

### Response:
 Awali, kulikuwa na wanafunzi 90 * 2 / 3 = <<90*2/3=60>>60 kwenye cafeteria.
Awali, kulikuwa na wanafunzi 90 - 60 = <<90-60=30>>30 nje ya cafeteria.
Kisha wanafunzi 30 * 1 / 3 = <<30*1/3=10>>10 walikimbia ndani.
Idadi ya wanafunzi kwenye cafeteria iliongezeka kwa 10 - 3 = <<10-3=7>>7.
Sasa kuna wanafunzi 60 + 7 = <<60+7=67>>67 kwenye cafeteria.
