0.25+0.3+0.16=?
0.6/(x-0.45)=0.25怎么算
解方程 0.3x+7x-0.25x=21.25
0.3x+7x-0.25x+=21.15
0.3x-x乘以0.25=21.15-7x
0.3x-x*0.25=21.15-7x解方程
0.3x+7x-0.25x=21.15
[(3/5-0.25)x4/7+0.3]÷3/4=?
x+0.25x=8分之7
(-5)×8×(-7×(-0.25)=?
24÷1.5-8.4×0.25 1+0.45÷0.9-8分之7 (5分之4-3分之2)X=12 0.4X+4×1.7=16.824÷1.5-8.4×0.25 1+0.45÷0.9-8分之7 (5分之4-3分之2)X=12 0.4X+4×1.7=16.8
4.5×0.8=(4+0.5)×0.8= 2.3×0.25+1.7×0.25= 0.45×99=
