How many small pink curlers are there? ** There are 16 curlers in all and ¼ of them are pink or 16 curlers / 4 = <<16/4=4>>4 pink curlers.
How many medium blue curlers are there? ** There are twice as many blue curlers as there are pink ones, so there are 4 pink x 2 = <<4*2=8>>8 blue curlers.
How many curlers are there in total? ** Together, there are 4 pink curlers + 8 blue curlers = <<4+8=12>>12 pink and blue curlers in Erin’s hair.
How many large green curlers does Erin have in her hair? ** The remaining curlers are green, so of the 16 total curlers – 12 pink and blue curlers = <<4=4>>4 green curlers are in Erin’s hair.
