Question #3735b

Answer 1

257% more correct answers than wrong answers.

Explanation:

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%

Answer 2

`44%` more right than wrong answers.

Explanation:

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.
