65×12÷15×16和134 266×9÷3怎么简便算

65×12÷15×16 =(13×5)×(3×4)÷15×16 =52×16 =832 134 +266×9÷3 =134+266×3 =134+798 =932

4/15*(1/6÷4/9) =4/15*3/8 =1/10

92-15×9÷3 =92-15x(9÷3) =92-15x3 =92-45 =47 朋友,请采纳正确答案,你们只提问,不采纳正确答案,回答都没有劲!!! 朋友,请【采纳答案】,您的采纳是我答题的动力,如果没有明白,请追问。谢谢。

15/16×9/10÷5/12 =27/32×12/5 =27×3/(8×5) =81/80 5/14÷10/21×5/7 =5/14×21/10×5/7 =15/28 3/20×14×5/7 =3/4×2 =3/2 =1又2分之1

9.6÷x=3 3x=9.6 x=9.6÷3 x=3.2

(2/3÷2/9)x(8/15÷16/7) =(2/3×9/2)x(8/15×7/16) =3×7/30 =7/10

2×13×5=(2×5)×13=10×13=130 51÷17×17÷51=51×117×17×151=1 12×7÷3÷7=12×7×13×17=4 25×13×4=(25×4)×13=100×13=1300 3×125×7×8=3×7×(125×8)=21×1000=21000 25×2×3×4×5=(25×4)×(2×5)×3=100×10×3=3000 25×28=25×(4×7)=25×4×7=100×7=700 ...

第一个题要是能写清楚点就好了 感觉有点乱 不过按顺序一一算能算出来 3/4×【(7/15-1/5)÷2/3】=3/4×3/2×(7/15-1/5) =3/4×3/2×(7/15-3/15) =3/4×3/2×4/15 = 3/10 3/5×(1/7+8/21÷2/3)=3/5×(1/7+4/7) =3/5×5/7=3/7 (2/3-3/4×1/3)÷5...

(15分之8+20分之9×3分之2)÷12分之1 =(15分之8+10分之3)÷12分之1 =(30分之16+30分之9)÷12分之1 =6分之5÷12分之1 =10

(15分之8+20分之9×3分之2)÷12分之1 =(15分之8+10分之3)÷12分之1 =(30分之16+30分之9)÷12分之1 =6分之5÷12分之1 =10
