Question

adam got 56 out 84 correct in his test what fraction of the mark did he get wrong

Answer 1

Answer:

simple , Adam got 56 correct out of 84 then wrong answers are 84 - 56 = 28

therefore fraction of wrong answers = 28/84

28/84 = 14/42 = 7/21 = 1/3

1/3 = 0.33 or 33.3%

i.e. he got 66.6% answers correct and 33.3% wrong
