Multiply across.\r
\n" ); document.write( "\n" ); document.write( "7*4 = 28\r
\n" ); document.write( "\n" ); document.write( "12 *5 = 60\r
\n" ); document.write( "\n" ); document.write( "\"28%2F60\" is your raw answer.\r
\n" ); document.write( "\n" ); document.write( "Most mathematicians have certain standards. One of those being that a fraction should always be in its simplest form.\r
\n" ); document.write( "\n" ); document.write( "What is the GCD(28,60). ~GCD is greatest common divisor.\r
\n" ); document.write( "\n" ); document.write( "If you are unsure, just divide by numbers you feel comfortable with.\r
\n" ); document.write( "\n" ); document.write( "Well 28 and 60 are both even so I can divide a 2.\r
\n" ); document.write( "\n" ); document.write( "But hey 14 and 30 are both even so I can divide a 2 again. (Dividing by 2 two times is equivalent to dividing by 4.)\r
\n" ); document.write( "\n" ); document.write( "7 and 15 have a GCD of 1. \r
\n" ); document.write( "\n" ); document.write( "\"7%2F15\" is the simplest answer.
