Josie took a long multiple choice,end of year vocabulary test. The ratio of the number of problems Jose got incorrect to the number of problems she got correct is 2:9.If Josie missed 8 questions, how many did she get correct?

Respuesta :

36. 
For every 2 wrong, she got 9 right, multiply this by four to get the four wrong, and the nine turns into 36

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.
