90 students audition for the school play. 1/3 of those who audition were cast six in major roles. What fraction of those who were cast got major roles. Write your answer as a decimal

1 answer

1/3 of the 90 students who auditioned means 90 * (1/3) = <<90*(1/3)=30>>30 students were cast.
Out of those 30 students, 6 got major roles.
Therefore, the fraction of those who were cast and got major roles is 6/30.
To write this fraction as a decimal, divide 6 by 30: 6/30 = 0.2.
So, the answer is 0.2.
