Respuesta :
Sonya got 8 questions right out of 10 questions in the first quiz, so she got 80% [(8/10) x 100 to get the percentage] of the questions right.
Apply this logic to 20 questions for the second quiz by multiplying 20 x 80% = 16 questions.
So she got 16 questions right on the second quiz.
Deduct 16 out of 20 (20 - 16 = 4) so she got 4 questions wrong on the second quiz.
Apply this logic to 20 questions for the second quiz by multiplying 20 x 80% = 16 questions.
So she got 16 questions right on the second quiz.
Deduct 16 out of 20 (20 - 16 = 4) so she got 4 questions wrong on the second quiz.
In mathematics, some of the most commonly used operations in soiving questions are addition, subtraction, multiplication, and division.
The number of questions Sonya got right is 16 questions and the number of questions she got wrong is 4 questions.
From the question, we know that:
Sonya got 8 out of 10 questions right on a quiz. We can convert this to a percentage score.
Therefore, the percentage of questions Sonya got right in this quiz is
8/10 x 100
= 80%
We are also told that she got the same score on a quiz that had 20 questions.
- To find the number of questions Sonya got right in the second quiz:
80% x 20 questions
= 16 questions.
Therefore, Sonya got 16 questions right.
- Solving for the number of questions, Sonya got wrong:
20 questions - 16 questions
= 4 questions
Therefore, Sonya got 4 questions wrong.
