137*135/136+135*1/136
=137*135/136+135/136
=135/136*(137+1)
=135/136*(136+2)
=135/136*136+135/136*2
=135+135/68
=136又67/68
=137*135/136+135/136
=135/136*(137+1)
=135/136*(136+2)
=135/136*136+135/136*2
=135+135/68
=136又67/68

137*135/136+135*1/136=(1+136)*135/136+135/136=135/136+136*135/136+135/136
=135/136+135+135/136=135+135/68=136又67/68
=135/136+135+135/136=135+135/68=136又67/68

=(136+1)(136-1)/136 + 135/136
=(136^2-1)/136+135/136
=136 - 1/136+135/136
=136又134/136
=136又67/68
=(136^2-1)/136+135/136
=136 - 1/136+135/136
=136又134/136
=136又67/68

(137×135)/136-(135×1)/136
=(137×135-135×1)/(136)
=[135×(137-1)]/136
=(135×136)/136
=135
=(137×135-135×1)/(136)
=[135×(137-1)]/136
=(135×136)/136
=135
