  • 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

    5/7×53+1/7×85

    =5/7×53+5/7×17

    =5/7×(53+17)

    =5/7×70

    =50
