4.5×0.8=(4+0.5)×0.8= 2.3×0.25+1.7×0.25= 0.45×99=
4.5×0.8=(4+0.5)×0.8= 2.3×0.25+1.7×0.25= 0.45×99=
4.5×0.8=(4+0.5)×0.8= 2.3×0.25+1.7×0.25= 0.45×99=
错
4.5×0.8=(4+0.5)×0.8= 2.3×0.25+1.7×0.25= 0.45×99=
4x+0.5x-4.5×0.8=0
4x+0.5x-4.5*0.8=0用方程怎么解
x÷0.8=4.5
(x-4.5)/0.8=2.5
解方程 6*9-8.5x=37 23.46-3x=4.6 4x+0.5x=4.5*0.8解方程 6*9-8.5x=37 23.46-3x=4.64x+0.5x=4.5*0.8
0.5:()=():0.8=0.625
5+0.5x=0.8
4×(0.5+0.8×4)=?用简便的方法计算
0.8+4=7.
4.5：10=0.8：x (解比例)
3.8x-0.8x=4.5
9:x=4.5/0.8解比例
x=4.5/0.8怎么算?
0.5x/0.8=5 x=?
3/4:x=5/16x:0.8=1/4 1.5x=4.5
列出综合算式1.6.4/8=0.8 3.4+3.8=7.2 0.8*7.2=5.762.4.2/6=0.7 0.7+0.8=1.5 6*1.5=4.653.15.5*0.6=9.3 0.6-0.1=0.5 9.3*0.54.35*1.4=49 4.5+1.75=6.25 49/6.25=7.84分开写
判断题:0.8+0.8+0.8+0.4+0.4=0.8*4=0.4*8
