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)
To find the fraction of those who were cast who got major roles, we divide the number of students with major roles by the total number of students who were cast.
Fraction of those who were cast with major roles = 6 major roles / (1/3) * 90 total students cast
= 6 major roles / 30 students cast
In decimal form, the fraction is 6/30 = 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 the length of the Advanced Trail compared to the Beginner's Trail, we need to multiply the ratios of the Advanced Trail to the Medium Trail (3.6) and the Medium Trail to the Beginner's Trail (1.2).
Length of the Advanced Trail / Length of the Beginner's Trail = 3.6 * 1.2 = 4.32
The Advanced Trail is 4.32 times as long as the Beginner's Trail.
