Dan is 1/6 his father's age.
\n" ); document.write( "d = \"1%2F6\"f
\n" ); document.write( "or
\n" ); document.write( "f = 6d
\n" ); document.write( ":
\n" ); document.write( "In 4 years, Dan will be 1/4 his fathers age.
\n" ); document.write( "d + 4 = \"1%2F4\"(f+4)
\n" ); document.write( ":
\n" ); document.write( "what is Dan's age?
\n" ); document.write( ":
\n" ); document.write( "Replace f with 6d in the last equation
\n" ); document.write( "d + 4 = \"1%2F4\"(6d + 4)
\n" ); document.write( "Multiply both sides by 4
\n" ); document.write( "4(d + 4) = 6d + 4
\n" ); document.write( ":
\n" ); document.write( "4d + 16 = 6d + 4
\n" ); document.write( ":
\n" ); document.write( "16 - 4 = 6d - 4d
\n" ); document.write( ":
\n" ); document.write( "12 = 2d
\n" ); document.write( ":
\n" ); document.write( "d = 6 yrs is Dan's age
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Check solution:
\n" ); document.write( "f = 6(6) = 36
\n" ); document.write( "\"In 4 years, Dan will be 1/4 his fathers age.\"
\n" ); document.write( "6 + 4 = 1/4 * 36 + 4
\n" ); document.write( " \n" ); document.write( "
\n" );
