58×11简便计算

58×11 =58×(10+1) =58×10+58 =580+58 =638

59x11/58 =(58+1)x11/58 =11+11/58 =11又58分之11

题干有误

根据58,6乘1,1=5,86×11,你能简便计算58,6×1,1-5,86 58.6*1.1-5.86 =5.86*11-5.86 =5.86*(11-1) =5.86*10 =58.6 乘法分配律

58.6×1.1-5.86 =58.6×(1.1-0.1) =58.6×1 =58.6

11.58-7又十一分之5 1点五八的和怎么简便就怎样算 11.58-7-5/11-1.58 =11.58-1.57-7-5/11 =3-5/11 =2又6/11

11×58等于多少横式加竖式加验算: 11×58(可以简便运算) =58×(10+1) =58×10+58×1 =580+58 =638 验算:638÷11=58 638÷58=11

11/10-1/4-1/3 =66/60-15/60-20/60 =51/60-20/60 =31/60 1/8×58+1/8×42+1/8 =1/8×(58+42+1) =1/8×(96+5) =1/8×96+1/8×5 =12+5/8 =12又5/8 2/5×1/5+40/100×4/5 =2/5×1/5+2/5×4/5 =2/5×(1/5+4/5) =2/5×1 =2/5 5/9÷5+5÷5/9 =5/9×1/5+5×9/5 =1/9+9 =...

58.6÷11=5.327...27 竖式如下:
