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

### Instruction:
Marla is mixing a particular shade of lilac that's 70% blue paint, 20% red paint, and the rest white paint. If she adds 140 ounces of blue paint, how many ounces of white paint does she add?

### Response:
 Kwanza tafuta jumla ya unga wa rangi ambao Marla anachanganya kwa kugawanya kiasi cha unga wa rangi ya buluu na asilimia ya unga wa rangi ambayo ni buluu: 140 unga / .7 = <<140/.7=200>>200 unga
Kisha, mara jumla ya unga wa rangi kwa asilimia ya unga ambao ni rangi nyeupe ili kupata idadi ya unga wa rangi nyeupe: 200 unga * 10% = <<200*10*.01=20>>20 unga
