document.write( "We read these words:\r\n" );
document.write( "\r\n" );
document.write( "\"...15 OUT OF 35 ON HER TEST...\" \r\n" );
document.write( "\r\n" );
document.write( " That's comparing 15 to 35.  \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then we ask ourselves: \"Comparing 15 to 35 is like comparing what to 100?\"\r\n" );
document.write( "\r\n" );
document.write( "Here's what you do.  You translate the first three words \"Comparing 15 to 35\"\r\n" );
document.write( "(I call numbers words).  Their translation is \"make the fraction \"15%2F35\"\".\r\n" );
document.write( "\r\n" );
document.write( "Translate the next three words: \"is like\".  That's just an = sign, so put\r\n" );
document.write( "an = after the \"15%2F35\" and you now have \"15%2F35=%22%22\"\r\n" );
document.write( "\r\n" );
document.write( "Now we come to this: \r\n" );
document.write( "\r\n" );
document.write( "WHAT PERCENT DID HE GET CORRECT?\r\n" );
document.write( " \r\n" );
document.write( "x is the \"what\".  That translates like the first \"comparing 15 to 35\" except\r\n" );
document.write( "we're now \"comparing x to 100\" like we compared 15 to 35. So we make the\r\n" );
document.write( "fraction \"\"x%2F100\"\" and put that on the other side of the = sign. \r\n" );
document.write( "\r\n" );
document.write( "Now we have the equation:\r\n" );
document.write( "\r\n" );
document.write( " \"15%2F35\"\"%22%22=%22%22\"\"x%2F100\"\r\n" );
document.write( "\r\n" );
document.write( "We solve that by cross-multiplying\r\n" );
document.write( "\r\n" );
document.write( "35x = 1500\r\n" );
document.write( "  x = \"1500%2F35\"\r\n" );
document.write( "  x = 43% rounding off from what the calculator gave me to a whole percent. \r\n" );
document.write( "    \r\n" );
document.write( "So 15 compares to 35 just like 43 compares to 100.\r\n" );
document.write( "\r\n" );
document.write( "(Rounded to tenths it was 42.9%)\r\n" );
document.write( "\r\n" );
document.write( "She FLUNKED! TOO BAD!  She should haved studied more. \r\n" );
