0.4×0.4×0.4=0.8×0.25x 怎么解
0.4×0.4×0.4=0.8×0.25x 怎么解
即0.2x=0.064 即x=0.064/0.2=0.064*5=0.32
0.4×0.4×0.4=0.8×0.25x 怎么解
0.8×0.25×0.4×12.5
0.4:0.25
简便计算 0.8×0.25×0.4×12.5 = = =
0.8×0.25×0.4×12.5简便计算
0.25×1.25×0.4×0.8简便计算
0.25×1.25×0.4×0.8怎么简便计算.
0.8*0.25*0.4*12.5的简便算法
0.8*0.25*0.4*12.5简便怎么算
0.25×(0.4+0.8)×12.5(递等式)
判断题:0.8+0.8+0.8+0.4+0.4=0.8*4=0.4*8
在下面算式中加上适当的运算符号和括号,使等式成立 .0.4 0.4 0.4 0.4 0.4 =0 0.4 0.4 0.4 0.4 0.4 =0.8打错了,是0.4 0.4 0.4 0.4 0.4=0 0.4 0.4 0.4 0.4 0.4=0
0.4/1.25=0.8/x
0.8:0.4=x:0.
