Answer:
[tex]\dfrac{7}{10}[/tex]
Explanation:
It is given that Jordan got 27 out of 90 correct in his test.
Total marks = 90
Correct answers = 27
Incorrect answers = 90 -27 = 63
The fraction of the marks he did wrong.
[tex]\dfrac{\text{Incorrect answers}}{\text{Total marks}}=\dfrac{63}{90}[/tex]
Simplify the above expression.
[tex]\dfrac{\text{Incorrect answers}}{\text{Total marks}}=\dfrac{7}{10}[/tex]
Therefore, the fraction of the marks he did wrong is 7/10.
