888.8×8-222.2×14-9×444.4 怎样简便计算
1÷1/2÷2/3÷3/4。÷99/100
1÷1/2÷2/3÷3/4。÷99/100
888.8×8-222.2×14-9×444.4
=222.2×32-222.2×14-18×222.2
=222.2×(32-14-18)
=222.2×0
=0
359÷27.3×1.254÷718×273÷125.4
=(359÷718)×(273÷27.3)×(1.254÷125.4)
=1/2×10×0.01
=0.5×0.1
=0.05
3又3/5×234+5555÷25/256+654.3×36
=18/5×234+5555×256/25+23554.8
=842.4+56883.2+23554.8
=81280.4
1÷1/2÷2/3÷3/4.÷99/100
=1×2×3/2×4/3..×100/99
=1×100
=100
