答案

(1)9.2×1.5÷3,

=13.8÷3,

=4.6;

(2)19.03-5.53-0.37,

=19.03-(5.53+0.37),

=19.03-5.9,

=13.13;

(3)86÷(8.6×25),

=86÷8.6÷25,

=10÷25,

=0.4;

(4)6.3×101-6.3,

=6.3×(100-1),

=6.3×100,

=630;

(5)1.8÷3.6×(0.9+1.2),

=1.8÷3.6×2.1,

=0.5×2.1,

=1.05;

(6)12÷0.125,

=12÷0.125÷8×8,

=12÷(0.125×8)×8,

=12÷1×8,

=12×8,

=96;

(7)18.21+25.93+1.79,

=(18.21+1.79)+25.93,

=20+25.93,

=45.93;

(8)59.6×18+59.6×81+59.6,

=59.6×(18+81+1),

=59.6×100,

=5960;

(9)33.02-(148.4-90.85)÷2.5,

=33.02-57.55÷2.5,

=33.02-23.02,

=10;

(10)[33.3-(17.4+3.1)]×6.05,

=[33.3-20.5]×6.05,

=12.8×6.05,

=77.44.
