(1)0.6×[(5-0.68)÷1.2]=0.6×[4.32÷1.2]

=0.6×3.6

=2.16

(2)4.3×10.2

=4.3×(10+0.2)

=4.3×10+4.3×0.2

=43+0.86

=43.86

(3)1.25×19.4×0.8

=1.25×0.8×19.4

=1×19.4

=19.4

(4)38.2÷0.25÷4

=38.2÷(0.25×4)

=38.2÷1

=38.2

(5)17.6-0.5×0.5-0.75

=17.6-0.25-0.75

=17.6-(0.25+0.75)

=17.6-1

=16.6

(6)0.8×(12.5+1.25)

=0.8×12.5+0.8×1.25

=10+1=11

=2.7×0.25+6.3×0.25,

=(2.7+6.3)×0.25,

=9×0.25,

=2.25;

(5)(6.02+2.8)÷0.4-2.05,=8.82÷0.4-2.05,

=22.05-2.05,

=20;

(6)3.08×3.5+6.2×3.08+3.08×0.3,=(3.5+6.2+0.3)×3.08,
