One-third of the 90 students who auditioned were cast, so there were (1/3) * 90 = <<(1/3)*90=30>>30 students who were cast.
Out of the 30 students who were cast, 6 got major roles.
So the fraction that got major roles is 6/30, which simplifies to 1/5.
As a decimal, that is equal to 0.2. Answer: \boxed{0.2}.
To determine the fraction of those who were cast that got major roles, we need to divide the number of students who got major roles by the total number of students cast.
The total number of students cast is one-third of the 90 students who auditioned, which is (1/3) * 90 = 30 students.
Therefore, the fraction of those who were cast that got major roles is 6/30 = 0.2.
So, the answer as a decimal is 0.2.
