Question

3.68x2.2-3.6x1.2怎么简算？

Answer 1

3.68*2.2-3.6*1.2
=（3.6+0.08）*2.2-3.6*1.2
=3.6+0.08*2.2
=3.776
=3.68*（1+1.2）-3.6*1.2
=0.08*1.2+3.68
=3.776
都可以，就是凑整数

Answer 2

3.68×2.2−3.6×1.2
=3.68（1+1.2）−3.6×1.2
=3.68+3.68×1.2−3.6×1.2
=3.68+（3.68−3.6）×1.2
=3.68+0.08×1.2
=3.68+0.096=3.776

Answer 3

3.68X2.2-3.6X1.2
=3.6X2.2+0.08X2.2-3.6X1.2
=3.6X(2.2-1.2)+0.176
=3.6X1+0.176
=3.776

Answer 4

不知道你是不是题目写漏了 ，希望能帮到你
3.68×2.2-3.68×1.2
＝3.68×（2.2-1.2）
＝3.68×1
＝3.68
