You got 131/3 % wrong and 862/3 % correct.
Obviously it was not a math test.
40% of 10 = 4 So four questions out of ten is answered correctly.
10/40 wrong means 30/40 correct 30/40 = 75% correct
That's 28 percent wrong. When your math improves, you'll be able to figure out that it also means 72 percent correct.
90% of 80 right means 10% of 80 wrong, which means 10/100 x 80 = 1/10 x 80 = 1/1 x 8 = 8 questions wrong.
10 answers were on the quiz.70 percent of 10 = 7Working out:70% = 70/100therefore70/100 = 7/10 (you can simply cross a 0 off each side of the fraction to get this)therefore seven questions out of ten are right.
You can get 20 questions wrong.
4 out of 10 is 40 percent
40% of 10 = 4 So four questions out of ten is answered correctly.
10 questions
67% or D+
10/40 wrong means 30/40 correct 30/40 = 75% correct
10 is the answer,because 100 - 80 = 20 divide that by 2 and you get the answer. 50 - 40 = 10
That's 28 percent wrong. When your math improves, you'll be able to figure out that it also means 72 percent correct.
10 can be wrong and 30 right; 30/40 = 75%
90% of 80 right means 10% of 80 wrong, which means 10/100 x 80 = 1/10 x 80 = 1/1 x 8 = 8 questions wrong.
8 wrong i.e. 32 right 10% of 40 is 4 80% = 8 x 4 = 32 40 - 32 = 8
To find the percentage, find the number of correct answers and divide by the total number of questions given. In this case it is (10-4)/10, or 60 percent.
