100 divided by 5 is 20. 100 minus 20 is 80. The answer is 1.
10 is the answer,because 100 - 80 = 20 divide that by 2 and you get the answer. 50 - 40 = 10
80%=80/100 80/100 x 50 questions = 40 correct answers. therefore 50 - 40 = 10 incorrect answers.
Oh, dude, if 80 percent of the questions were answered correctly, that means 20 percent were wrong. So, if 5 questions were missed, that's 20 percent of the total questions. To find out how many questions were answered correctly, you just need to calculate 80 percent of the total questions. Math, man, it's like magic but with numbers.
