Damian is taking a multiple choice test with a total of 40 points available. Each question is worth exactly 4 points. What would be Damian's test score (out of 40) if he got 4 questions wrong? What would be his score if he got xx questions wrong?

36/40 or 90%

Step-by-step explanation:

First convert it to a fraction, which in this case is 36/40.

To find the percentage, we need to find an equivalent fraction with the denominator of 100. Multiply both numerator & denominator by 100.

36/40 × 100/100

= (36 × 100/40) × 1/100 = 90/100

Therefore, the answer is 90%.

If you are using a calculator, simply enter 36÷40×100, which will give you 90 as the percentage.
