Answer 1

In the test we have a 10/10 fraction of questions, which could also mean 100%, if Rita answered 9 questions correctly, we have a fraction of 9/10, which is 90%, therefore she answered 1 question incorrectly, the fraction will be 1/10, which represents 10% of the test. The option will be C 1/10
