  • 4/5÷(3/4-1/2)=1/5

    (128+32)÷4/5=200

    5/8×4/15÷3/4=2/9

    34÷(2/3+3/4)=24

    1÷(1/2+1/3)÷(3/4×15%)=32/3

    23.4÷(1+30%)=18

    72÷(1/5+1)×2/5=24

    乙 20÷(1-3/5)=50 甲 50-20=30

    40×(1+50%)÷(1-25%)=80

    (3又1/2×6)×4/7=12

    (2又1/3-1.5)×(1/3-0.2)=1/9

    (18-12)÷2/5=15

    1÷8/9+2.4×0.8=3.045

    (10-3又1/2÷0.7)÷1/7=35

    (0.25+0.025)÷5=0.055

    (5.6-0.25×5)÷0.125=34.8

    [(1.1-0.7)×2.5+4]÷5=1

    (542-84×3)×0.2=58
