Algebra.Com's Answer #234907 by meay7c(10)![]() ![]() You can put this solution on YOUR website! Here we have a test with 20 questions. With each question being worth 3 points.\r \n" ); document.write( "\n" ); document.write( "Let's multiply the number of questions by the point value to determine the total number of points possible for the test:\r \n" ); document.write( "\n" ); document.write( "20 * 3 = 60.\r \n" ); document.write( "\n" ); document.write( "So the test is worth 60 points.\r \n" ); document.write( "\n" ); document.write( "The student scored 48 points out of 60 points. Next we determine the percentage the student answered correct:\r \n" ); document.write( "\n" ); document.write( "48 / 60 = .80 \r \n" ); document.write( "\n" ); document.write( "The student scored 80% or .80 on his / her test. Now we take this .80 to determine the actual amount of problems the student got correct.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "There were 20 questions, so the student got 80% of the 20 questions correct. We use multiplication as the word \"of\" denotes multiplication:\r \n" ); document.write( "\n" ); document.write( ".80 of 20 = .80 * 20 = 16 questions answered correctly.\r \n" ); document.write( "\n" ); document.write( "You can check your answer also: \n" ); document.write( "16 questions answered correctly * 3 points = 48 Yes!!!\r \n" ); document.write( "\n" ); document.write( "Good Luck :-) \n" ); document.write( " |
