The first step in solving almost all fractional equations is to multiply all the terms by the lowest common denominator...here that is 40...so we get
\n" ); document.write( "7/8 + 2/5 = x/20
\n" ); document.write( "40(7/8 + 2/5 = x/20)
\n" ); document.write( "35 + 16 = 2x
\n" ); document.write( "2x = 51
\n" ); document.write( "x = 51/2
\n" ); document.write( "
\n" );
