1. if coach adami has 7 out of 28 students who failed test 1, what percentage of students passed test 1?

Explanation:

12)

Step1: Calculate the fraction of students with As

To find the fraction, we take the number of students with As (18) divided by the total number of students (30). So, the fraction is $\frac{18}{30}$.

Step2: Convert the fraction to a percentage

To convert a fraction to a percentage, we multiply it by 100. So, $\frac{18}{30} \times 100 = 60$.

Step1: Find the number of students without As

The total number of students is 30, and 18 have As. So, the number of students without As is $30 - 18 = 12$.

Step2: Calculate the fraction of students without As

The fraction is $\frac{12}{30}$.

Step3: Convert the fraction to a percentage

Multiply the fraction by 100: $\frac{12}{30} \times 100 = 40$.

Step1: Find the number of students who passed

The total number of students is 28, and 7 failed. So, the number of students who passed is $28 - 7 = 21$.

Step2: Calculate the fraction of students who passed

The fraction is $\frac{21}{28}$.

Step3: Convert the fraction to a percentage

Multiply the fraction by 100: $\frac{21}{28} \times 100 = 75$.

Answer:

60%
