Question

If 90% of the answers were correct then what percent were incorrect what percent were incorrect

Answer 1

10% of the answers would be wrong beacuse 100% is also equal to 1, and if only 90% of the answers were incorrect, that would be equal to 0.9. To get from 0.9 to 1, you add 0.1, or 10%

Answer 2

10%. Because 100% -90% is 10%
