1 $\"3%2F5\"$ x - 2 $\"1%2F2\"$ = $\"7%2F10\"$
\n" ); document.write( "8X/5-5/2=7/10
\n" ); document.write( "8X/5=7/10+5/2
\n" ); document.write( "8X/5=(7+5*5)/10
\n" ); document.write( "8X/5=(7+25)/10
\n" ); document.write( "8X/5=32/10
\n" ); document.write( "10*8X=5*32
\n" ); document.write( "80X=160
\n" ); document.write( "X=160/80
\n" ); document.write( "X=2 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "8*2/5-5/2=7/10
\n" ); document.write( "16/5-5/2=7/10
\n" ); document.write( "(2*16-5*5)/10=7/10
\n" ); document.write( "(32-25)/10=7/10
\n" ); document.write( "7/10=7/10 \n" ); document.write( "

\n" );
