Answer 1

简便计算2.2×4.6+22×0.55-0.22=2.2×4.6+2.2×10×0.55-2.2×0.1=2.2×（4.6+5.5-0.1）=2.2×10=22

Answer 2

2.2*46+22*0.55-0.22=2.2*46+2.2*5.5-2.2*0.1=2.2*(46+5.5-0.1)=2.2*51.4=113.08

Answer 3

运用乘法分配律，简便运算如下：
2.2×4.6＋22×0.55－0.22
＝0.22×10×4.6＋0.22×100×0.55－0.22
＝0.22×46＋0.22×55－0.22
＝0.22×(46＋55－1)
＝0.22×100
＝22

Answer 4

2.2×4.6+22×0.55-0.22
=2.2×4.6+2.2×10×0.55-2.2×0.1
=2.2×(4.6+5.5-0.1)
=22

Answer 5
