简便:18/0.36*5.8 (2)9.66+3.65-2.66+0.35 (3)29.7/(5.85/0.65) (4)3.84-2.7*0.64
你好
18/0.36*5.8
=18/(0.18*2)*5.8
=18÷0.18÷2*5.8
=100*2.9
=290
9.66+3.65-2.66+0.35
=(9.66-2.66)+(3.65+0.35 )
=7+4
=11
29.7/(5.85/0.65)
=29.7/9
=3.3
3.84-2.7*0.64
=6*0.64-2.7*0.64
=(6-2.7)*0.64
=3.3*0.64
=3*0.64+0.3+0.64
=1.92+0.192
=2.112
