If you have 75 questions how many question will you need to get correct to get a 90%

68 Questions

Step-by-step explanation:

When using the symbol % (percent), it means that percent of 1. So for example: 90% = 0.9 because 90/100 simplifies to 9/10, which is also 0.9.

In this problem, the question basically is: What is 90% of 75? The math equation to use would be: 75×0.9.

   75

x   .9

67.5

Doing the math, 90% of 75 is 67.5. In the problem, we don't know if you can get a half-credit for a problem, so we have to round 67.5 to the nearest whole number. The number 67.5 rounds up to 68.

So, if you have 75 questions, you need to get correct 68 questions in order to get a 90%.
