题目内容
脱式计算，能简算的要简算：
| 46.5×99+46.5 | 12.5÷2.5÷0.4 | 2.6×1.9÷2.6×1.9 |
| （7.7+1.54）÷0.7 | 10.8÷[（4.62-1.92）×4] | 2.6×（2.139÷9.3×6.2） |
（1）46.5×99+46.5
=46.5×（99+1）
=46.5×100
=4650
（2）12.5÷2.5÷0.4
=12.5÷（2.5×0.4）
=12.5÷1
=12.5
（3）2.6×1.9÷2.6×1.9
=2.6÷2.6×1.9×1.9
=1×1.9×1.9
=3.61
（4）（7.7+1.54）÷0.7
=9.24÷0.7
=13.2
（5）10.8÷[（4.62-1.92）×4]
=10.8÷[2.7×4]
=10.8÷10.8
=1
（6）2.6×（2.139÷9.3×6.2）
=2.6×（0.23×6.2）
=2.6×1.426
=3.7076
=46.5×（99+1）
=46.5×100
=4650
（2）12.5÷2.5÷0.4
=12.5÷（2.5×0.4）
=12.5÷1
=12.5
（3）2.6×1.9÷2.6×1.9
=2.6÷2.6×1.9×1.9
=1×1.9×1.9
=3.61
（4）（7.7+1.54）÷0.7
=9.24÷0.7
=13.2
（5）10.8÷[（4.62-1.92）×4]
=10.8÷[2.7×4]
=10.8÷10.8
=1
（6）2.6×（2.139÷9.3×6.2）
=2.6×（0.23×6.2）
=2.6×1.426
=3.7076
