0.25+0.3+0.16=?
用简便算法计算:0.125×3.2-0.25×0.16=
(x-0.16)÷0.3=1.8怎么解,
0.1+0.2+0.3+...+0.8+0.9+0.12+0.14+0.16+...+0.88 =
计算根号0.16×0.25×400
计算题0.1+0.3+0.5+0.7+0.9+0.11+0.16+...+0.97+0.99=
解方程:(4x-0.2)/0.3=(3x-1.1)/0.4+(0.16-0.7x)/0.06
求方程解:(x-0.16):0.3=1.8:1 (要有过程)
0.3x-x*0.25=21.15-7x
0.3x+7x-0.25x+=21.15
0.3x-x乘以0.25=21.15-7x
【1+0.3】x+【1+0.25】【960-x】=1228 过程!
解方程:0.25x+3=0.3x+2
