Question

3.6×0.2=	12.5×0.8=
0.32+6.4=	0.2×0.37=
0.43×0.2=	3.7×10=
5.73-5.73×0=	32.7×0.99+0.01×32.7=

Answer 1

分析：小數(shù)加減法的計(jì)算法則：小數(shù)點(diǎn)對(duì)齊，從低位加起，橫線下面的小數(shù)點(diǎn)要和上面的對(duì)齊，末尾有“0”一般要把“0”去掉．
小數(shù)乘法的計(jì)算法則：按整數(shù)乘法的計(jì)算法則進(jìn)行計(jì)算，因數(shù)里面一共有幾位小數(shù)，就從積的末尾數(shù)出幾位點(diǎn)上小數(shù)點(diǎn)．據(jù)此解答．

解答：解：3.6×0.2=0.72
12.5×0.8=10
0.32+6.4=6.72
0.2×0.37=0.074
0.43×0.2=0.086
3.7×10=37
5.73-5.73×0=5.73
32.7×0.99+0.01×32.7
=32.7×（0.99+0.01）
=32.7
故答案為：0.72；100；6.72；0.074；0.086；37；5.73；32.7．

點(diǎn)評(píng)：本題考查了學(xué)生小數(shù)加減法和小數(shù)乘法的掌握情況．
