What number minus 33 1/3% OF IT equals 30. \r\n" );
document.write( "I know the answer is 45,\r\n" );
document.write( "but I do not know how to set up to get the answer. Please help!\r\n" );
document.write( "\r\n" );
document.write( "Reason it out this way:\r\n" );
document.write( "Suppose you knew the answer was X.  Then if you took 33 1/3 \r\n" );
document.write( "percent of that X and then minused that off the X, you'd have \r\n" );
document.write( "to get 30, wouldn't you?\r\n" );
document.write( "\r\n" );
document.write( "So take 33 1/3% of X.  That just means to take a third of X and\r\n" );
document.write( "get X/3. Now minus that off the X.  To do that you just put down \r\n" );
document.write( "the X and then minus X/3 off of it, like this\r\n" );
document.write( "\r\n" );
document.write( "     X - X/3\r\n" );
document.write( "\r\n" );
document.write( "That would have to equal to 30. So put it equal to 30:\r\n" );
document.write( "\r\n" );
document.write( "     X - X/3 = 30\r\n" );
document.write( "\r\n" );
document.write( "Now solve that for X.  If you can't solve that, post again.\r\n" );
document.write( "\r\n" );
document.write( "You'll get X = 45 when you solve it.\r\n" );
document.write( "\r\n" );
