11.9÷0.6-0.7÷0.6
=（11.9-0.7）÷0.6
=11.2÷0.6
=56/3

11.9÷0.6-0.7÷0.6用簡便方法=（11.9-0.7）÷0.6
=11.2÷0.6
=11.2÷3/5
=11.2×5/3
=56/3
9.6×7.7÷0.3÷11怎麼簡便計算？
3樓：匿名使用者
這道題的簡便計算。
可以先計算9.6÷0.3=32。
在計算7.7÷11=0.7。
所以結果就是32×0.7=22.4。
4樓：匿名使用者
這道題的簡便演算法是利用交換結合律。9.6÷0.3x(7、7÷11)二32x0、7二22.4。這道題的簡便計算方法看明白了嗎？謝謝！
簡算：計算0.7×13/11-6.6×3/7-2.2÷7/3+0.7×9/11+3.3×8/7
5樓：lh我愛我家
解：0.7×
du13/11-6.6×zhi3/7-2.2÷dao7/3+0.7×9/11+3.3×8/7
=0.7×13/11+0.7×9/11-6.6×3/7+3.3×8/7-2.2÷7/3
=0.7（
回13/11+9/11）
答-3/7（-6.6+8.8）-2.2×3/7=0.7×2+2.2×3/7-2.2×3/7=1.4
6樓：匿名使用者
0.7×13/11-6.6×3/7-2.2÷7/3+0.7×9/11+3.3×8/7
=（0.7×13/11+0.7×9/11）+(6.6×4/7-6.6×3/7-6.6*1/7)
=0.7×(13/11+9/11）+6.6×(4/7-3/7-1/7)
=0.7×2+6.6*0
=1.7
如有幫助回，請採納。答謝謝
