Assuming that all questions score equally, you can miss out at most 7. And then need to get them all correct.
22
You can miss 10% of questions, or 12 questions
Assuming the questions are all weighted the same, you can miss 5 and score 90%.
54
To achieve a score of 90% on a 56-question test, you would need to answer 90% of the questions correctly, which is 50.4 questions. Since you cannot answer a fraction of a question, you would need to answer at least 51 questions correctly. Therefore, you can afford to miss 56 - 51 = 5 questions and still achieve a 90% score on the test.

Answering 63 questions correctly - is 70% of 90 questions.
Assuming the questions are all weighted the same, you can miss 5 and score 90%.
To achieve a score of 90 on a 30-question test, you need to answer at least 27 questions correctly, as 90% of 30 is 27. This means you can miss up to 3 questions. Therefore, you can miss a maximum of 3 questions to still score 90.

To achieve a score of 90% on a 56-question test, you would need to answer 90% of the questions correctly, which is 50.4 questions. Since you cannot answer a fraction of a question, you would need to answer at least 51 questions correctly. Therefore, you can afford to miss 56 - 51 = 5 questions and still achieve a 90% score on the test.
If the TABE test has 90 questions, how many I can miss to pass the test?
To get at least 90% on a 50 question test, you can miss no more than 5 questions.
Provided that all the ones that you do not miss are correct, then 30% of 90 = 90*30/100 = 27.
You can't get 90% in a test with 32 questions. However, if calculated the answer would be 3.2. i.e., you would miss 3.2 questions to get 90%. This can happen when the examiner gives you marks even for a partially correct answer.
90% of 27 = 27*90/100 = 24.3 So you MUST answer 25 questions - ie all but 2 - AND get them all correct!
