70% of 31 questions is 31*70/100 = 21.7 questions.
However, since you cannot have 0.7 questions, the answer is one of:
21 questions = 68% or 22 questions = 71%
31% of 70= 31% * 70= 0.31 * 70= 21.7
You can get 60 questions wrong and get a 70 percent but if you get 61 wrong you are at a 69.5 percent.
30
14 of them.
You can miss 31.5 questions. 105*70%(.70)=73.5 105-73.5= 31.5
31% of 70= 31% * 70= 0.31 * 70= 21.7
To find 70 percent of 60 questions, you would multiply 60 by 0.70 (which is the decimal form of 70 percent). This calculation would result in 42 questions. Therefore, 70 percent of 60 questions is 42 questions.
You can get 60 questions wrong and get a 70 percent but if you get 61 wrong you are at a 69.5 percent.
