99.99*0.8.11*2.8谁能帮我解决简便算法,要过程...

99.99*0.8+11.11*2.8 =11.11*(9*0.8)+11.11*2.8 =11.11*7.2+11.11*2.8 =11.11*(7.2+2.8) =11.11*10 =111.1

99.99×0.8+11.11×2.8 =11.11×0.8×9+11.11×2.8 =11.11×(7.2+2.8) =11.11×10 =111.1 ======================================== 柳浪闻莺各位芝麻竭诚为您解答 您的采纳是我们坚持百度的动力 =========================================

=11.11*(7.2+2.8) =111.1

简算: 99.9x0.8+11.1x2.8 =11.1x9x0.8+11.1x2.8 =11.1x7.2+11.1x2.8 =11.1x(7.2+2.8) =11.1x10 =111

(1)3.74×2.85+8.15×3.74-3.74=3.74×(2.85+8.15-1)=3.74×10=37.4;(2)99.99×0.8+11.11×2.8=11.11×7.2+11.11×2.8=11.11×(7.2+2.8)=11.11×10=111.1;(3)31.4×0.68+314×0.032=314×0.068+314×0.032=314×(0.068+0.032)=314×0.1=31.4;(4...
