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?
18
70% of 15 is 10.5 so it is 4.5 questions
No more than 19. You can do it!
Assuming that you get all your answers correct (can you rely on that?), you can miss 12.
14 miss 35 correct 35/49 = 0.714 = 71.4%

Not more than 11.
Assuming that you get all your answers correct (can you rely on that?), you can miss 12.
14 miss 35 correct 35/49 = 0.714 = 71.4%
70% of 12 is 8.4 and 12 minus 8.4 = 3.6
64, of course. Unless you mean how many can you miss and still pass... 70% of 64 is 44.8, so you need 45 to pass so you can miss 19.
2 * (50 - x) = 70 50 - x = 35 x = 15 You can miss 15 questions.
60 questions can be missed.
1(95-x)=70 95x=70 x 25x
28 x 70% = 19.6 which means you need 20/28 which will give you 71 percent 19/28 would give you 68 percent
