Rachel is twice as old as Rona and Collete's age is half the age of Rona's. If Rona is [NUMBER] years old, what is the difference between the age of Collete and Rachel?
Rachel's age is 8 x 2 = <<8*2=16>>16.
Collete's age is 8 / 2 = <<8/2=4>>4.
Therefore the difference between their age is 16 - 4 = <<16-4=12>>12.
