题目内容
| 计算下列各题,能简算的要简算. 6.33×101-6.33 | 1.56×1.7+0.44×1.7 |
| 1.8×[(3.41-2.9)÷0.03] | 0.125×32×2.5. |
(1)6.33×101-6.33,
=6.33×(101-1),
=6.33×100,
=633;
(2)1.56×1.7+0.44×1.7,
=1.7×(1.56+0.44),
=1.7×2,
=3.4;
(3)1.8×[(3.41-2.9)÷0.03],
=1.8×[0.51÷0.03],
=1.8×17,
=30.6;
(4)0.125×32×2.5,
=(0.125×8)×(4×2.5),
=1×10,
=10.
=6.33×(101-1),
=6.33×100,
=633;
