计算下面各题,怎样简便就怎样算.①468×5+232×5 ②900÷25÷4 ③15.6-4.47-5.53+6.4 ④23.76-(5.76-4.23) ⑤19×96+962÷74 ⑥400-(1300÷65+35) ⑦6.75+0.5-4.86 ⑧88×125.

①468×5+232×5
=(468+232)×5,
=700×5,
=3500;

②900÷25÷4
=900÷(25×4),
=900÷100,
=9;

③15.6-4.47-5.53+6.4
=15.6+6.4-(4.47+5.53),
=22-10,
=12;

④23.76-(5.76-4.23)
=23.76-5.76+4.23,
=18+4.23,
=22.23;

⑤19×96+962÷74
=1824+13,
=1837;

⑥400-(1300÷65+35)
=400-(20+35),
=400-55,
=345;

⑦6.75+0.5-4.86
=7.25-4.86,
=2.39;

⑧88×125
=11×(8×125),
=11×1000,
=11000.
