$\"%285%2F7%29%2F%289%2F14%29=w%2B1\"$
\n" ); document.write( " $\"%285%2F7%29%2A%2814%2F9%29=w%2B1\"$ When dividing fractions, you multiply the 1st fraction by the reciprocal of the 2nd (ie $\"%281%2F2%29%2F%281%2F3%29=%281%2F2%29%283%2F1%29=3%2F2\"$
\n" ); document.write( " $\"%285%2F1%29%2A%282%2F9%29=w%2B1\"$ Notice that 7 goes into 14 2 times so $\"14%2F7=2\"$
\n" ); document.write( " $\"10%2F9-1=w%2Bcross%281-1%29\"$ Subtract 1 from both sides
\n" ); document.write( " $\"10%2F9-1=w\"$
\n" ); document.write( " $\"10%2F9-9%2F9=w\"$
\n" ); document.write( " $\"%2810-9%29%2F9=w\"$
\n" ); document.write( " $\"1%2F9=w\"$
\n" ); document.write( "So
\n" ); document.write( " $\"w=1%2F9\"$
\n" ); document.write( "

\n" ); document.write( "Check:
\n" ); document.write( " $\"%285%2F7%29%2F%289%2F14%29=1%2F9%2B1\"$
\n" ); document.write( " $\"10%2F9=1%2F9%2B9%2F9\"$
\n" ); document.write( " $\"10%2F9=10%2F9\"$ works \n" ); document.write( "

\n" );
