问题描述:
在下面的五个算式中加上适当的运算符号和括号,使符合左右两边相等.
0.5______0.5______0.5______05______0.5=0
0.5______0.5______0.5______05______0.5=0.5
0.5______0.5______0.5______05______0.5=1
0.5______0.5______0.5______05______0.5=1.5
0.5______0.5______0.5______05______0.5=2.
答
根据题意可得:
0.5×(0.5-0.5)×0.5×0.5=0;
0.5+0.5-0.5+0.5-0.5=0.5;
0.5×(0.5-0.5)+0.5+0.5=1;
0.5+0.5+(0.5-0.5)+0.5=1.5;
0.5÷0.5÷0.5÷05×0.5=2.
