257% more correct answers than wrong answers.

The wrong answers equal the total or 100%.

25-18 = 7 wrong answers

# 18/7 xx 100 # = % correct answers to wrong answers

#18/7 xx 100# = 257%

#44%# more right than wrong answers.

Tina scored 18 out of 25 correct.

As a percent:
#18/25 xx100% = 72%# of the answers correct.

She must have had #25-18 = 7# answers wrong.
As a percent:
#7/25 xx100% = 28%# of the answers wrong.

The difference in percent between the right and wrong answers is:

#72%-28% = 44%#

She had 44% more right answers than wrong answers.
