50 is half of 100; 50 x 2 = 100 35 x 2 = 70 answer is 70%
Percentage increase from 50 to 70 is (20/50) x 100 = 40% Percentage decrease from 70 to 50 is (20/70) x 100 = 28.5714%
It is not possible to answer the question without knowing how much of the total each one is worth. If they are both equally important, then the answer is 50% but they are rarely (if ever) equally important. If the test grade is worth x percent of the total - not your grade but how much weight it carries in the total - then the average is [x*70+(1-x)*30]/100
6 wrong means 14 correct. 14/20 * 100% is 70%.
To do this problem, you set up a proportion: 50 percent of 100 is equal to what (x) percent of 70? It should look like this: 50/100 = x/70 To solve this problem, divide 50 by 100: .5 = x/70 To finish the equation, times both sides by 70: (.5)(70) = (70)(x/70) [The x70 and /70 cancel each other out] 35 = x So, 50% of 70 is 35.
70 percent of 60 is 42. The points don't enter into it.
2 * (50 - x) = 70 50 - x = 35 x = 15 You can miss 15 questions.
The " 70% " score represents the fraction of the questions that you answered correctly.If you answered 70% correctly, you missed the remaining 30% .30% of 50 = 0.3 x 50 = 15 .
In order to score 70 or below on a 50-question test, you must answer at least 15 of them wrong.
It is 70%
To obtain that answer you multiply 35 by .70. The answer is thus 24.5.
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?

50% of 70 = 50% * 70 = 0.5 * 70 = 35
50% of 70= 50% * 70= 0.5 * 70= 35
70% of 50= 70% * 50= 0.70 * 50= 35
In order to score an 80 percent on a 70 question test, one can afford approximately 14 errors. This question can be calculated by taking 56 divided by 70,which equals 0.8. Take 0.8 and multiply that by 100 to get 80.
