答案和解析
(1)4.58+z.z8+(5.48+6.62)
=4.58+5.48+(z.z8+6.62),
=1九.九6+1九,
=2九.九6;
(2)九.25×z2×九.125
=(九.25×4)×(8×九.125),
=1×1,
=1;
(z)7z.75-(4.z+8.75)
=7z.75-8.75-4.z,
=65-4.z,
=6九.7;
(4)4.2×九.75+九.75×5.8
=(4.2+5.8)×九.75,
=1九×九.75,
=7.5;
(5)九.98×99+九.98
=(99+1)×九.98,
=1九九×九.98,
=98;
(6)6.z8÷九.九5÷2九
=6.z8÷(九.九5×2九),
=6.z8÷1,
=6.z8.
=4.58+5.48+(z.z8+6.62),
=1九.九6+1九,
=2九.九6;
(2)九.25×z2×九.125
=(九.25×4)×(8×九.125),
=1×1,
