0.95*8.6-7.6*0.9请用简便方法计算
0.95*8.6-7.6*0.9请用简便方法计算
参考：0.95*8.6-7.6*0.9 = 1.33
能简便的用简便方法计算．
75+8.95+10.25 6.38-1.8+3.62
95÷1.25÷0.8 9.4×5-10.6．
7×9.9+0.1×0.7 13.8+15.6÷0.4．
85×1.25+0.85×1.75 2.15×0.9+21.5×0.11．
（1）75+8.95+10.25
=75+（8.95+10.25）
=75+19.2
=94.2
（2）6.38-1.8+3.62
=（6.38+3.62）-1.8
=10-1.8
=8.2
（3）95÷1.25÷0.8
=95÷（1.25×0.8）
=95÷1
=95
（4）9.4×5-10.6
=47-10.6
=36.4
（5）7×9.9+0.1×0.7
=7×9.9+0.01×7
=7×（9.9+0.01）
=7×9.91
=7×（10-0.09）
=7×10-7×0.09
=70-0.63
=69.37
（6）13.8+15.6÷0.4
=13.8+39
=52.8
（7）85×1.25+0.85×1.75
=106.25+1.4875
=107.7375
（8）2.15×0.9+21.5×0.11
=2.15×0.9+2.15×1.1
=2.15×（0.9+1.1）
=2.15×2
=4.3
