.分析:根据小数乘法的意义,用乘法依次解答即可.
解答:解:0.1×10=1
0.01×3=0.03
0.01×10=0.1
0.01×92=0.92
0.001×10=0.01
0.001×48=0.048
0.001×837=0.837
所以,10个0.1是1,3个0.1是0.3;10个0.01是0.1,92个0.01是0.92;10个0.001是0.01,48个0.001是 0.048,837个0.001是0.837.
故答案为:1,0.3,0.1,0.92,0.01,0.048,0.837.
0.01×3=0.03
0.01×10=0.1
0.01×92=0.92
0.001×10=0.01
0.001×48=0.048
0.001×837=0.837
所以,10个0.1是1,3个0.1是0.3;10个0.01是0.1,92个0.01是0.92;10个0.001是0.01,48个0.001是 0.048,837个0.001是0.837.
故答案为:1,0.3,0.1,0.92,0.01,0.048,0.837.
