1、0.125×96
解析：此题先利用减法分配律把96转换成（100-4），再利用乘法结合律，使得运算简便。
0.125×96
=0.125×（100-4）
=0.125×100-0.125×4
=12.5-0.25
=12
2、33333x44444+66666x77778
解析：33333x44444可以变换为66666×22222，提取公约66666，变换为66666×(22222+77778)再用乘法分配律来脱式计算。
33333x44444+66666x77778
=33333×2×22222+66666×77778
=66666×22222+66666×77778
=66666×(22222+77778)
=66666×100000
=6666600000
3、30-（3.8+0.75）
解析：此题主要利用加法结合律和分配律，先把3.8变换成（4-0.2），0.75变换成（1-0.25），再利用加法交换律，先算整数，再算小数，最后利用加法结合律，去掉括号运算。
30-（3.8+0.75）
=30-[（4-0.2）+（1-0.25）]
=30-[（4+1）-（0.2+0.25）]
=30-（5-0.45）
=30-5+0.45
=25.45
4、3.6×2.5
解析：此题先利用乘法分配律把3.6转化成9×0.4，再利用乘法交换律凑整使得运算简便。
3.6×2.5
＝9×0.4×2.5
＝1×9
＝9
5、555×15+111×25
解析：此题先把555变换成111×5，再利用运用乘法分配律和提取公约数来脱式计算。
555×15+111×25
=111×5×15+111×25
=111×（5×15）+111×25
=111×75+111×25
=111×（75+25）
=111×100
=11100
6、98×8/99
解析：此题先利用减法分配律把98转换成（99-1），再利用乘法结合律使得运算简便。
98×8/99
=（99-1）×8/99
=99×8/99-1×8/99
=8-8/99
=7又91/99
7、0.9+9.9+99.9+999.9+9999.9
解析：此题先找规律，5个数都差0.1可凑整，先利用凑整法变换一下，再利用加法结合律（a+b）+c=a+（b+c），来进行脱式计算。
0.9+9.9+99.9+999.9+9999.9
=（1-0.1）+（10-0.1）+（100-0.1）+（1000-0.1）+（10000-0.1）
=1+10+100+1000+10000-0.1×5
