求简便计算一道数学算式
8又5分之3 x 2.7+62x14%+35x0.86
答
原式=0.86x27+62x(1-0.86)+35x0.86
=（27+35-62））x0.86+62
=62
希望采纳谢谢~~纯手算的~~
答
8又5分之3 x 2.7+62x14%+35x0.86
=8.6 x 2.7+62x0.14+3.5x8.6
=8.6 x 2.7+6.2x1.4+3.5x8.6
=8.6x6.2+6.2x1.4
=6.2x(8.6+1.4)
=62
答
8又5分之3 x 2.7+62x14%+35x0.86
=8.6×2.7+62×0.14+3.5×8.6
=8.6×2.7+3.5×8.6+6.2×1.4
=8.6×（2.7+3.5）+6.2×1.4
=8.6×6.2+6.2×1.4
=6.2×（8.6+1.4）
=6.2×10
=62
