答案

(1)23.4-8.54-1.46,

=23.4-(8.54+1.46),

=23.4-10,

=13.4;

(2)15.25-3.1+0.75-4.9,

=(15.25+0.75)-(3.1+4.9),

=16-8,

=8;

(3)26×101-26,

=26×(101-1),

=26×100,

=2600;

(4)73+3.4+27+5.6,

=(73+27)+(3.4+5.6),

=100+9,

=109;

(5)363×7+237×7,

=7×(363+237),

=7×600,

=4200;

(6)101×39,

=(100+1)×39,

=100×39+39,

=3939.
