题目内容
用递等式计算(怎样简便就怎样计算).
| 5.4+[8×(6.34-3.59)]0.95×10.1 | 10.48+22.56÷4.7×5.4 | 4.6÷(0.23×2.5) |
(1)5.4+[8×(6.34-3.59)]
=5.4+[8×2.75]
=5.4+22
=27.4;
(2)0.95×10.1
=0.95×(10+0.1)
=0.95×10+0.95×0.1
=9.5+0.095
=9.595;
(3)10.48+22.56÷4.7×5.4
=10.48+4.8×5.4
=10.48+25.92
=36.4;
(4)4.6÷(0.23×2.5)
=4.6÷0.575
=8.
