Answer: She got 36 correct answers.
Step-by-step explanation:
Since we have given that
Ratio of the number of problems she got incorrect to the number of problems she got correct = 2:9
Number of incorrect answers = 8
Let the number of incorrect answers be 2x
Let the number of correct answers be 9x.
So, According to question, we get that
[tex]2x=8\\\\x=\dfrac{8}{2}\\\\x=4[/tex]
So, the number of correct answers would be
[tex]9x=9\times 4=36[/tex]
Hence, she got 36 correct answers.
