15 wrong

40 percent wrong questions. To calculate the percentage 6 divided by 15 and multiplied by 100.

7 wrong out of 22 questions = 31.8% wrong. 15 correct out of 22 questions = 68.2% correct. I hope it wasn't a math test.

73 questions on the test, all worth the same credit. Score 79% means you got -- 58 correct (79.452%) -- 15 wrong (20.548%)

70% of 15 is 10.5 so it is 4.5 questions

15 questions.

not more than 15

52*28% = 14.56, so a minimum of 15 questions.

70% of 50 is 35 so the answer is 15

You can get at most 22 questions wrong, otherwise you will score less than 70 %. To get 70% right you can get 100 % - 70 % = 30 % wrong 30% of 75 = 30/100 x 75 = 22.5 I assume you can't get 1/2 a question wrong, so you can get at most 22 questions wrong otherwise you will score less than 70 %.

100*12/15 = 80 percent
