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.
To find the fraction of those who were cast and got major roles, we need to divide the number of students who got major roles (6) by the total number of students who were cast.
Fraction = (Number of students who got major roles) / (Total number of students who were cast)
Fraction = 6 / (1/3 * 90)
To simplify this expression, we can multiply the numerator and denominator by the reciprocal of 1/3, which is 3/1.
Fraction = (6 * 3) / (1 * 90)
Fraction = 18 / 90
Now, we can simplify the fraction to its lowest terms. Both the numerator and denominator are divisible by 9.
Fraction = 2 / 10
Finally, we can express this fraction as a decimal by dividing the numerator by the denominator.
Fraction = 2 ÷ 10 = 0.2
Therefore, the fraction of those who were cast and got major roles is 0.2.
At Point Pleasant Park, the Advanced Trail is 3.6 times as long as the Medium Trail, and the Medium Trail is 1.2 times as long as the Beginner's Trail. How many times as long as the Beginner’s Trail is the Advanced Trail? Write your answer as a decimal.(1 point)
To find out how many times as long the Advanced Trail is compared to the Beginner's Trail, we need to multiply the lengths of each trail together.
Let's assume the length of the Beginner's Trail is 1 unit.
According to the given information, the Medium Trail is 1.2 times as long as the Beginner's Trail. So, the length of the Medium Trail is 1 * 1.2 = 1.2 units.
Similarly, the Advanced Trail is 3.6 times as long as the Medium Trail. So, the length of the Advanced Trail is 1.2 * 3.6 = 4.32 units.
Therefore, the Advanced Trail is 4.32 times as long as the Beginner's Trail.
So, the answer is 4.32.
here are 7/8
cups of sugar in a canister in the kitchen. Ms. Johnson used 1/2
of the sugar when she was preparing dessert for her daughter's birthday cake. How much sugar did she use?(1 point)
To find out how much sugar Ms. Johnson used for the dessert, we need to multiply the fraction of sugar used (1/2) by the total amount of sugar in the canister (7/8 cup).
To multiply fractions, we multiply the numerators together and the denominators together.
Fraction used = (1/2) * (7/8)
Numerator = 1 * 7 = 7
Denominator = 2 * 8 = 16
Fraction used = 7/16
Therefore, Ms. Johnson used 7/16 cup of sugar for the dessert.
