分子:0.4*0.25分母:0.4*0.75=0.4*0.25*3直接约分,0.4*0.25/0.4*0.75=0.4*0.25/0.4*0.25*3=1/3
8×[0.75-0.25×(4-2)]=8×（0.75-0.25×2)=8×（0.75-0.5)=8×0.25=2
=0.75*4*6+0.75/0.25=3*6+3=21
0.25*39+0.75*27=0.25*3(13+27)=0.25*3*4*10=1*30=30
36*(0.25+0.75-0.25+0.75)=36*(0.25+0.75)+36*(-0.25+0.75)=36*1+36*0.5=36+18=54
36*（0.25+0.75-0.25+0.75）=36*（1+0.5）=36+18=54
（0.25+0.75）+（0.125+0.875）-3.25＝1+1-3.25＝-1.25
0.75+0.075÷0.25+0.25=0.75+0.075x4+0.25=0.75+0.3+0.25=0.75+0.25+0.3=1+0.3=1.3
你好!是这样算的：（0.75+0.75）-（0.25+0.25）=1.5-0.5=1
0.74*0.25+0.75=0.74*0.25+0.25*3=0.47*(0.25+3)=0.47*3.25=1.5275再问：取某种花色的扑克牌10张,分别是1~10。牌面向下无顺序叠一起,任意抽
这还要简便运算吗0.75/0.25=33*1.8=5.4
22.32+（0.25+0.75）再答：=22.32+1=23.32
0.25:0.75=（0.25×100）：（0.75×100）=25:75=1:3
5/13=0.3846153846153846很有意思的数字
等于-3
=-0.75-2.5+0.25=-0.75+0.25-2.5=-0.5-2.5=-3这个是最详细的解法
方程是啥?如果为：x^0.75-x^0.25=0.75令t=x^0.25,则x^0.75=t^3方程化为:t^3-t=0.75,解得：t=1.26255112740716x=t^4=2.5409486
5-(0.25-0.75)再问：错再答：5+0.5再答：5.5再答：要变号再问：恩
