answer the following questions using both a fraction and a percentage.

1. what is the percentage of students that are grade 10 and attend the afternoon session for the art program?
2. of the students that attend the morning session, what percentage are of the 6th grade level?
3. of the 8th graders students who attend the art program, what percentage attend the morning session?

Explanation:

Step1: Calculate percentage for question 1

The number of students in 10th grade who attend the afternoon session is 26, and the total number of students is 100. The percentage formula is $\frac{\text{Number of relevant students}}{\text{Total number of students}}\times100\%$. So, $\frac{26}{100}\times100\% = 26\%$.

Step2: Calculate percentage for question 2

The number of 6th - grade students who attend the morning session is 15, and the total number of morning - session students is 45. The percentage is $\frac{15}{45}\times100\%=\frac{1}{3}\times100\%\approx 33.33\%$.

Step3: Calculate percentage for question 3

The number of 8th - grade students who attend the morning session is 18, and the total number of 8th - grade students is 39. The percentage is $\frac{18}{39}\times100\%\approx 46.15\%$.

Answer:

1. 26%
2. Approximately 33.33%
3. Approximately 46.15%
