4/9÷(3/5-1/3)×5/6

=4/9÷4/15×5/6

=4/9×15/4×5/6

=25/18

4/9÷[(5/6-3/4)x2/3]

2楼:妙酒

4/9÷[(5/6-3/4)x2/3]

=4/9÷(1/12x2/3)

=4/9÷1/3

=4/3

3楼:山塘人山塘人

4/9÷[(5/6-3/4)×2/3]

=4/9÷[(10/12-9/12)×2/3]=4/9÷(1/12 ×2/3)

=4/9÷1/18

=4/9×18=8

3/8x[8/9÷(5/6一3/4)]怎么简便计算

4楼:匿名用户

=3/8×[8/9÷1/12]

=3/8×8/9÷1/12

=1/3×12=4

5楼:匿名用户

=1/3÷1/12=4

脱式计算:1/3÷7/9×5/6 12/5÷(3/4+1/3)-1/3 15÷[5/7×(2/3-1/5)]

6楼:匿名用户

1.1/3÷7/9×5/6

=1/3*9/7*5/6

=3/7*5/6

=5/14

2.12/5÷(3/4+1/3)-1/3

=12/5÷13/12-1/3

=5/13-1/3

=2/39

3.15÷[5/7×(2/3-1/5)]

=15÷[5/7×7/15]

=15÷1/3=45

4/15÷(1又4/9-2/3×5/6)+5/6

7楼:西域小镇

解:4/15÷(1又4/9-2/3×5/6)+5/6=4/15÷(13/9-5/9)+5/6

=4/15*(9/8)+5/6

=3/10+5/6

=9/30+25/30

=34/30

=17/15

8楼:kz菜鸟无敌

4/15÷(1又4/9-2/3×5/6)+5/6=4/15÷(13/9-5/9)+5/6

=4/15÷4/9 + 5/6

=4/15 x 9/4 + 5/6

=3/5 + 5/6

=18/30+25/30

=43/30

(5/6-3/4)÷(2/3+4/9) (1-1/6×2/5)÷7/9

9楼:新野旁观者

(5/6-3/4)÷(2/3+4/9)

=1/12÷10/9

=3/40

(1-1/6×2/5)÷7/9

=(1-1/15)÷7/9

=14/15÷7/9

=6/5

(5/9+1/13)×9+4/13

=5/9×9+1/13×9+4/13

=5+(9/13+4/13)

=5+1

=65/4-(3/4-1/8)-3/8

=(5/4-3/4)-(3/8-1/8)

=1/2-1/4

=1/4

10楼:kz菜鸟无敌

(5/6-3/4)÷(2/3+4/9)

= (10/12-9/12)÷(6/9+4/9)=1/12÷10/9

=1/12 x 9/10

=3/40

~~~~~~ (1-1/6×2/5)÷7/9=(1-1/15) ÷ 7/9

=14/15 x 9/7

=6/5

~~~~~

(5/9+1/13)×9+4/13

=5/9 x 9 + 1/13 x 9 +4/13=5 + 9/13 + 4/13

=5 + 1

=6~~~~~

5/4-(3/4-1/8)-3/8

=5/4 - ( 6/8 - 1/8 ) - 3/8=5/4 - 5/8 -3/8

=5/4 - 1

=1/4

梯等式计算(能简便的要简便)

4/9×[3/4-(9/16-3/8)]

=4/9*3/4-4/9*9/16+4/9*3/8=1/3-1/4+1/6

=1/4

36÷[(5/6-2/3)×3]

=36 / [(5/6-4/6)*3]

=36 / 1/2

=72(1/15+2/17)×15×17

=1/15*15+2/17*17*15

=1+2*15

=31(4/3-3/4÷3)×12

=4/3*1/2-1/4*1/2

=2/3-1/8
