333*777-222*666分之999*333,简算,

333*777-222*666分之999*333,简算,
=999×333/(333×777-333×444)
=999/(777-444)
=999/333
=3

=[(111×9)×(111×3)]/[(111×3)×(111×7)-(111×2)×(111×6)]
=[(111×111)×(9×3)] / [(111×111)×(3×7)-(111×111)×(2×6)]
=[(111×111)×27] / [(111×111)×21-(111×111)×12]
=[(111×111)×27] / [(111×111)×(21-12)]
=[(111×111)×27] / [(111×111)×9]
=27/9
