### Instruction:
Ali is collecting bottle caps. He has 125 bottle caps. He has red ones and green ones. If he has 50 red caps, what percentage of caps are green?

### Response:
 Jumla ya vikorokoro vya chupa ni 125.
Idadi ya vikorokoro vya rangi nyekundu ni 50.
Idadi ya vikorokoro vya rangi ya kijani ni 125 - 50 = <<125-50=75>>75
Asilimia ya vikorokoro vya rangi ya kijani ni 75 / 125 * 100 = <<75/125*100=60>>60%
