【答案】:
15.4,0.154,1.54,1.54,0.0154,0.154,0.0154,154,0.00154
【解析】:
根據(jù)14×11=154,數(shù)因數(shù)中小數(shù)位數(shù)確定積的小數(shù)位數(shù)。
14×1.1:14×11=154,1.1有1位小數(shù),積為15.4;
1.4×0.11:1.4有1位小數(shù),0.11有2位小數(shù),共3位小數(shù),積為0.154;
0.14×11:0.14有2位小數(shù),積為1.54;
1.4×1.1:1.4有1位小數(shù),1.1有1位小數(shù),共2位小數(shù),積為1.54;
0.14×0.11:0.14有2位小數(shù),0.11有2位小數(shù),共4位小數(shù),積為0.0154;
0.14×1.1:0.14有2位小數(shù),1.1有1位小數(shù),共3位小數(shù),積為0.154;
1.4×0.011:1.4有1位小數(shù),0.011有3位小數(shù),共4位小數(shù),積為0.0154;
1.4×110:1.4×11=15.4,110=11×10,積為15.4×10=154;
0.014×0.11:0.014有3位小數(shù),0.11有2位小數(shù),共5位小數(shù),積為0.00154。
