(6.8-6.8×0.55)÷3.66+7.85-5.37
=6.8x(1-0.55)÷3.66+7.85-5.4+0.03
=3.9x2x0.45÷3.66+2.45+0.03
=3.9x0.9÷3÷1.22+2.48
=1.17÷1.22+2.48
=117/122+2+12/25
=2+(117x25+12x122)/3050
=2+4389/3050
=3+1339/3050
=3又3050分之1339

解:原式=(6.8-3.74)÷3.66+7.85-5.37
=3.06÷3.66+7.85-5.37
=51/61+7.85-5.37
=51/61+2.48
=51/61+62/25
=3右482/1525
=3.06÷3.66+7.85-5.37
=51/61+7.85-5.37
=51/61+2.48
=51/61+62/25
=3右482/1525
