81)=01.19+35*0.6×0.6×（10.19
2.19+35*0.1111×（4.3.19+35*0.81=0.81=0.19+35*(0.2－7.2)=2.19+0.19+35=35.（27.7.6×1.81=36*0.6×10.2=7.4-10）×17=1700
4.2-0.2）=76
3.6+82.0.8+15.9＋35*0

Answer 2

145x929292／292929－460x458／459
=145×92×10101/(29×10101)-(459+1)×458/459
=145×92/29-（459×458/459+458/459）
=5×92-458-458/459
=460-458-458/459
=2-458/459
=1又1/459

Answer 3

Answer 4

9999/10000*7/10+1111/10000*27/10
=9999/10000*7/10+1111/10000*9*27/10*1/9
=9999/10000*7/10+9999/10000*3/10
=9999/10000*(7/10+3/10)
=9999/10000*1
=9999/10000
