Answer:

\dfrac{7}{10}

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.

\dfrac{\text{Incorrect answers}}{\text{Total marks}}=\dfrac{63}{90}

Simplify the above expression.

\dfrac{\text{Incorrect answers}}{\text{Total marks}}=\dfrac{7}{10}

Therefore, the fraction of the marks he did wrong is 7/10.

90-27=63

therefore the student got 63 questions wrong in a test of 90

i.e 63/90

In-s [12.5K]

I believe the answer is: D. A company that has eight employees chooses not to hire a disabled person because it is a small, private business and the owner cannot afford to make modifications to the building.


When this condition occur, the small company is exempted from the act because forcing them to make modification would most likely make them forced to fire existing employees. The government saw this as a negative outcome that increase the number of unemployment.
