257% more correct answers than wrong answers.

The wrong answers equal the total or 100%.

25-18 = 7 wrong answers

$\frac{18}{7} \times 100$ $18/7 xx 100$ = % correct answers to wrong answers

$\frac{18}{7} \times 100$ $18/7 xx 100$ = 257%

$44 %$ $44%$ more right than wrong answers.

Tina scored 18 out of 25 correct.

As a percent:
$\frac{18}{25} \times 100 % = 72 %$ $18/25 xx100% = 72%$ of the answers correct.

She must have had $25 - 18 = 7$ $25-18 = 7$ answers wrong.
As a percent:
$\frac{7}{25} \times 100 % = 28 %$ $7/25 xx100% = 28%$ of the answers wrong.

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

$72 % - 28 % = 44 %$ $72%-28% = 44%$

She had 44% more right answers than wrong answers.
