Answer: 90%



If there are 50 questions and only 5 are answered incorrectly, it leaves him with 45 questions answered correctly.


In order to get the percentage you will need to put 45 over 50 and multiply it against 100%.


45/50 x 100%

0.9 x 100%

=90%
45/50
get the 50 to 100 so multiply by 2
then you have to multiply 45 by 2 which equals 99
90%
