did you mean 84% or did you mean .84%.
\n" ); document.write( "if you meant 84%, then .84% is equal to .0084
\n" ); document.write( "if you meant 84%, then 84% is equal to.84
\n" ); document.write( "25 is the total number of problems.
\n" ); document.write( "x is the number of correct solutions.
\n" ); document.write( "if the ratio is 84%, then the ratio is .84 and you get .84 = x / 25.
\n" ); document.write( "solve for x to get x = 25 * .84 = 21
\n" ); document.write( "if the ratio is .84%, then the ratio is .0084 and you get .0084 = x / 25.
\n" ); document.write( "solve for x to get x = 25 * .0084 = .21
\n" ); document.write( "i doubt you meant .84%.
\n" ); document.write( "if 84%, then 21 is the least number of problems that the student needs to have correct.
\n" ); document.write( "if you said the answer was 21/25, then that would not be correct because it's a ratio and not a number.
\n" ); document.write( "i believe the answer should be 21.\r
