0.625×5.8+5/8×3.2+62.5% =0.625x5.8+0.625x3.2+0.625 =0.625x(5.8+3.2+1) =0.625x10 =62.5; 2017×2015/2016 =(2016+1)x2015/216 =2016x2015/2016+1x2015/2016 =2015+2015/2016 =2015又2015/2016; (1/2+1/3+1/6)x24 =1/2x24+1/3x24+1/6x24 =1...

(1)2.64×1.7-2.64×0.7 =2.64×(1.7-0.7) =2.64×1 =2.64 (2)31.5×1.07-3.15×0.7 =3.15×10.7-3.15×0.7 =3.15×(10.7-0.7) =3.15×10 =31.5 (3)2.7×5.7-2.7+5.3×2.7 =2.7×(5.7-1+5.3) =2.7×10 =27 (4)0.625÷0.125×0.8 =(0.625×0.8)×8÷...

0.625加2/7+8分之三 0.625+2/7+3/8 =5/8+2/7+3/8 =5/8+3/8+2/7 =1+2/7 =1又2/7 谢谢,请采纳

325-162÷36×24 =325-162×2/3 =325-54×2 =325-108 =217 ( 3分之1+6分之1+9分之1)除以36分之1 =(6/18+3/18+2/18)×36 =(11/18)×36 =11×2 =22 解方程 1、4分之3x+5分之2x=69 15x+8x=69×20 23x=69×20 x=60 2、1.25:0.25=x:1.6 0.25x=1.6×1.25 x...
