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?
He has 75 green caps because 125 - 50 = <<125-50=75>>75
The proportion of caps that are green is .6 because 75 / 125 = <<75/125=.6>>.6
The percentage that are green is 60 because .6 x 100% = <<60=60>>60%
#### 60
