  • |-16.2|+|-2又1/3|+3又2/3-10.7

    =16.2+2又1/3+3又2/3-10.7

    =(16.2-10.7)+(2又1/3+3又2/3)

    =5.5+6

    =11.5

    -64÷3又1/5x5/8

    =-64×5/8×5/8

    =-40×5/8

    =-25

    2/5÷(-2又2/5)-8/21x(-1又3/4)-0.5÷2x7/2

    =-1/6+1/3-1/4×7/2

    =1/6-7/8

    =-17/24

    -1÷(1/3-1/2)

    =-1÷(-1/6)

    =6

    (5/12+2/3-3/4)x12

    =5/12×12+2/3×12-3/4×12

    =5+8-9

    =4

    -5÷(-1又2/7)x4/5x(-2又1/4)÷7

    =-5×(-7/9)×4/5×(-9/4)×1/7

    =-(5×4/5)×(7/9×9/4)×1/7

    =-4×7/4×1/7

    =-1

    (1/4+1/12+7/18-1/36)÷1/36-2x(-1/3)

    =(1/4+1/12+7/18-1/36)×36+2/3

    =1/4×36+1/12×36+7/18×36-1/36×36+2/3

    =9+3+14-1+2/3

    =25又2/3

    3.95x6-1.45x6+(7/48-5/6+1/6)x24-3又1/2

    =(3.95-1.45)×6+(7/48×24-5/6×24+1/6×24)-3又1/2

    =2.5×6+(3.5-20+4)-3.5

    =15-12.5-3.5

    =-6
