第二题先算除法,化到12/14,再减,1/14

第三题分配

第四题先把后面变成4/95/6,再提取5/6,分配律,5/6

第五题变成45/4-4/51/4,直接算,四又五分之四

第六题先算中括号里的,再算外面,70/11

题:5/9X(9/5+18) 5/9X5/6+4/9÷6/5

=5/9×9/5+5/9×18 =5/9×5/6+4/9×5/6

=1+10 =(5/9+4/9)×5/6

=11 =1×5/6

=5/6

13/14-15/28÷5/8 4÷4/5-4/5÷4

=13/14-15/28×8/5 =4×5/4-4/5×1/4

=13/14-3/7×2 =5+1/5

=13/14-6/7 =26/5

=1/14

(5/6-3/4)÷3/8 7/11÷[2/5-(1-7/10)}

=(5/6-3/4)×8/3 =7/11÷[2/5-3/10]

=5/6×8/3-3/4×8/3 =7/11÷1/10

=20/9-2 =70/11

=2/9

5/9X(9/5+18) 5/9X5/6+4/9÷6/5

=5/9×9/5+5/9×18 =5/9×5/6+4/9×5/6

=1+10 =(5/9+4/9)×5/6

=11 =1×5/6

=5/6

13/14-15/28÷5/8 4÷4/5-4/5÷4

=13/14-15/28×8/5 =4×5/4-4/5×1/4

=13/14-3/7×2 =5+1/5

=13/14-6/7 =26/5

=1/14

(5/6-3/4)÷3/8 7/11÷[2/5-(1-7/10)}

=(5/6-3/4)×8/3 =7/11÷[2/5-3/10]

=5/6×8/3-3/4×8/3 =7/11÷1/10

=20/9-2 =70/11

=2/9

两道题,小学六年级数学分数四则混合运算

1、120×3/4 =90(米) 第二天修的长度

120-90=30(米) 第二天比天少修的长度

2、4/5 × (1-1/2 -1/5) =6/25(公顷)

120-120×3/4

4/5-1/2-1/5=1/10
