So basically there was a test with 72 questions and you got x number of them wrong, and got 70%. So... You have to find out what 70% of 72 is. All you have to do is multiply 0.70 by 72. Which equals 50.4 50 represents the number of questions you got right out of 72. So, 50/72 = roughly 70% -------------------------------------------------------------------------------------------------- 72 - 50 = 22 SO. To answer you question, you can miss 22 questions out of 72 to get 70 percent. Why does it sound like you're trying to go all lazy on a test?
