Andrew got a 95% on the test. If there were 80 questions on the test, and every question worth the same, how many questions did

Lemur [1.5K]

Answer:

Out of 80 questions Andrew did 76 questions correctly.

Step-by-step explanation:

Total number of questions is 80.

It is given that he got 95% on the test. It means he answered 95% of the total questions correctly.

First we have to calculate 95% of 80.

$80\times \frac{95}{100}=76$

The 95% of 80 is 76. So, 76 answers are correct.

Therefore out of 80 Andrew did 76 questions correctly.
