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

### Instruction:
Carla is dividing up chores for her two kids, Anna and Billy. She wants each of them to spend the same number of minutes working. Sweeping takes 3 minutes per room, washing the dishes takes 2 minutes per dish, and doing laundry takes 9 minutes per load. If Anna does the sweeping for 10 rooms and Billy does two loads of laundry, how many dishes should Billy wash so they spend the same amount of time doing chores?

### Response:
 Kwanza tafuta muda jumla ambao Billy anatumia kufua nguo: mizigo 2 * dakika 9/mzigo = <<2*9=18>>18 dakika
Kisha tafuta muda jumla ambao Anna anatumia kusafisha: dakika 3/chumba * vyumba 10 = <<3*10=30>>30 dakika
Kisha tafuta tofauti ya muda ambayo Anna amefanya kazi zaidi kuliko Billy: dakika 30 - dakika 18 = <<30-18=12>>12 dakika
Kisha gawanya tofauti ya muda kwa muda wa kuosha sahani moja ili kupata idadi ya sahani ambazo Billy anapaswa kuosha ili wafanye kazi kwa muda sawa na Anna: dakika 12 / dakika 2/sahani = <<12/2=6>>6 sahani
