Ninety students auditioned for the school play. One-third of those who auditioned were cast, 6 in major roles. What fraction of those who were cast got major roles? Write your answer as a decimal.(1 point)
One-third of the 90 students who auditioned were cast, so 1/3 * 90 = <<1/3*90=30>>30 students were cast.
Out of the 30 students who were cast, 6 got major roles, so 6/30 = <<6/30=0.2>>0.2 of those who were cast got major roles.
Answer: \boxed{0.2}.
Let's call the length of the Beginner's Trail "x".
The Medium Trail is 1.2 times as long as the Beginner's Trail, so its length is 1.2x.
The Advanced Trail is 3.6 times as long as the Medium Trail, so its length is 3.6 * (1.2x).
Simplifying this expression, the length of the Advanced Trail is 4.32x.
Therefore, the Advanced Trail is 4.32 times as long as the Beginner's Trail.
Answer: \boxed{4.32}.
To find out how much sugar Ms. Johnson used, we need to multiply 7/8 cups by 1/2.
Multiplying the numerators gives us 7 * 1 = 7.
Multiplying the denominators gives us 8 * 2 = 16.
So, Ms. Johnson used 7/16 cups of sugar.
Answer: \boxed{\frac{7}{16}}.
To find out how much Mr. Romanov paid for 9.3 gallons of gas at $3.30 a gallon, we need to multiply the number of gallons by the cost per gallon.
Multiplying 9.3 gallons by $3.30 gives us:
9.3 * $3.30 = $30.69
Therefore, Mr. Romanov paid $30.69 for 9.3 gallons of gas.
Answer: \boxed{\$30.69}.
To find out what fraction of the campers at Rosewood Performing Arts Camp play the guitar, we need to multiply the fractions representing the proportions of campers who play an instrument and those who play the guitar.
One-third of the campers play an instrument, so the fraction is 1/3.
Two-fifths of those campers play the guitar, so the fraction is 2/5.
Multiplying 1/3 by 2/5 gives us:
(1/3) * (2/5) = 2/15
Therefore, 2/15 of the campers at Rosewood Performing Arts Camp play the guitar.
Answer: \boxed{\frac{2}{15}}.
