Answer 1

2.2×36.3等于多少5.4×40.7等于多少0.33×79.8等于多少3.11×0.77等于多？
2.2×36.3等于79.86
5.4×40.7等于219.78
0.33×79.8等于26.334
3.11×0.77等于2.3947

Answer 2

2.2×36.3=79.86
5.4×40.7=219.78
0.33×79.8=26.334
3.11×0.77=2.3947

Answer 3

2.2*36.3=79.86
4*40.7=162.8
0.33*76.8=25.344
3.11*0.77=2.3947
都是二位小数以下的乘法运算，可以列竖式计算。不是很难的，要通过练习学会噢。关键有二点。一是列竖式都是两数的末位对齐，积的小数点位数是乘数小数位数的和。

Answer 4

2.2×36.3=79.86
5.4×40.7=219.78
0.33×79.8=26.334
3.11×0.77=2.3947

Answer 5

2.2x36.3
=（2+0.2）x36.3
=72.6+7.26
=79.86
5.4x40.7
=（5+0.4）x40.7
=203.5+16.28
=219.78
0.33x79.8
=（0.3+0.03）x79.8
=23.94+2.394
=26.334
3.11x0.77
=3.11（0.7+0.07）
=2.177+0.2177
=2.3947
