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

### Instruction:
Erin put 16 curlers in her hair. One-fourth of the curlers are small pink ones. There are twice as many medium blue curlers as there are pink ones. The rest are large green curlers. How many large green curlers does Erin have in her hair?

### Response:
The small curlers are pink or blue. There are 16 curlers in all and ¼ of them are pink or blue, so 16 curlers / 4 = <<16/4=4>>4 pink or blue curlers.
There are twice as many blue curlers as there are pink ones, so there are 4 pink curlers * 2 = <<4*2=8>>8 blue curlers.
Together, there are 4 pink curlers + 8 blue curlers = <<4+8=12>>12 pink and blue curlers in Erin’s hair.
The remaining curlers are green, so there are 16 curlers total – 12 pink and blue curlers = <<16-12=4>>4 green curlers.
