In a zoo, 21% of the animals are reptiles and 11% are birds. There are a total of 1,500 animals in the zoo. Which proportion can be solved for r, the number of reptiles?

A. 21/100 = r/1,500
B. 11/21 = r/1,500
C. 11/100 = r/1,500
D. 100/21 = r/1,500

I'm not that good with percents. All I would like is some help, not answers, but just something to help me solve this.
