Answer 1

Ответ:

1. х-скільки відсотків зробив

30/100%=22/х

х=22*100%/30

х≈73%

2. 73%-60%=13%

3. 100%-73%=27%

Answer 2

To solve this problem, we need to calculate the percentage of the student's score in relation to the maximum possible score, as well as the percentage by which the student's score exceeds the minimum passing score and how much the maximum score exceeds the student's score.

Let's break down the problem into three parts:

1. Percentage of the student's score:

To find the percentage of the student's score, we can use the formula:

Percentage = (Student's Score / Maximum Possible Score) * 100

In this case, the student's score is 22 and the maximum possible score is 30. Plugging these values into the formula, we get:

Percentage = (22 / 30) * 100 = 73.33%

Therefore, the student's score is 73.33%.

2. Percentage by which the student's score exceeds the minimum passing score:

To find the percentage by which the student's score exceeds the minimum passing score, we can use the formula:

Percentage = ((Student's Score - Minimum Passing Score) / Minimum Passing Score) * 100

In this case, the minimum passing score is 18. Plugging in the values, we get:

Percentage = ((22 - 18) / 18) * 100 = 22.22%

Therefore, the student's score exceeds the minimum passing score by 22.22%.

3. Percentage by which the maximum score exceeds the student's score:

To find the percentage by which the maximum score exceeds the student's score, we can use the formula:

Percentage = ((Maximum Possible Score - Student's Score) / Student's Score) * 100

In this case, the maximum possible score is 30. Plugging in the values, we get:

Percentage = ((30 - 22) / 22) * 100 = 36.36%

Therefore, the maximum score exceeds the student's score by 36.36%.

To summarize: 1. The student's score is 73.33% of the maximum possible score. 2. The student's score exceeds the minimum passing score by 22.22%. 3. The maximum score exceeds the student's score by 36.36%.
