Question

7.34×99+73.4×1.1-734×0.1的简便计算怎么做

Answer 1

简便计算如下图：
7.34×99+73.4×1.1-734×0.1
=7.34×99+7.34×11-7.34×10
=7.34×(99+11-10)
=7.34×100
=734
分析：看这个题，它的每一个乘数734，第1
个7.34×99我们不变，第2个73.4×1.1我们把它变一下，但结果不变，变成7.34x11，第3个734×0.1变成7.34×10，就是7.34x（99+11-10），结果是7.34×100=734

Answer 2

7.34×99+73.4×1.1-734×0.1
=7.34×(100-1)+73.4×(1+0.1)-73.4
=734-7.34+73.4+7.34-73.4
=734

Answer 3

7.34×99+73.4×1.1-734×0.1
=7.34×99+7.34×11-7.34×10
=7.34×(99+11-10)
=7.34×100
=734

Answer 4

7.34×99+73.4×1.1-734×0.1
=7.34×99+7.34×11-7.34×10
=7.34×(99+11-10)
=7.34×100
=734

Answer 5

7.34×（100-1）+73.4×（1+0.1）- 734×0.1=734-7.34+73.4+7.34-73.4=734
