    10-5.4= 4÷20= 3.5×200= 1.5-0.06=

    0.75÷15= 0.4×0.8= 4×0.25= 0.36+1.54=

    1.01×99= 420÷35= 25×12= 135÷0.5=

    3/4 + 1/4 = 2 + 4/9 = 3 - 2/3 = 3/4 - 1/2=

    1/6 + 1/2 -1/6 = 7.5-(2.5+3.8)= 7/8 + 3/8 =

    3/10 +1/5 = 4/5 - 7/10 = 2 - 1/6 -1/3 =

    0.51÷17= 32.8+19= 5.2÷1.3= 1.6×0.4=

    4.9×0.7= 1÷5= 6÷12= 0.87-0.49=
