If Linda got 93 % correct then she must have got 7% wrong.
Find 7% of 80.
%287%2F100%29+%2A+80+=+5.6
Mathematically she has 5.6 questions wrong.
Given that she received part marks for one of the questions then there were 6 questions which did not receive full marks. (One question she has received 0.4 marks for.)
