0.75÷0.25÷0.2 =75/25*10/2 =15

3/4×(9/8)+0.75÷8/7+2÷(4/3) =3/4×(9/8)+3/4x7/8+2x3/4 =3/4x(9/8+7/8+2) =3/4x(2+2) =3/4x4 =3 谢谢,请采纳

解:0.75÷0.25=3 0.125×8=1 4.8÷0.3=16 0.86÷2=0.43 0.56÷28=0.02 0.36÷0.4=0.9 0.64÷0.8=0.8 0.7×9=6.3 3.6÷24=0.15 0.8×1.1=0.88 7.2+12.8=20 46.7-3.8=42.9 12.8÷4=3.2 5.2÷13=0.4 12.5÷5=2.5 1.64+4.1=5.74 10÷20=0.5 24÷15=1.6 8.65×10=86...

(1)6.8×0.75÷0.5,=68×(0.75÷0.5),=68×1.5,=102;(2)13.5÷2.5-2.75,=5.4-2.75,=2.65;(3)0.125×0.25×32,=0.125×0.25×4×8,=(0.125×8)×(0.25×4),=1×1,=1;(4)0.9+9.9+99.9+0.3,=(1-0.1)+(10-0.1)+(100-0.1)+0.3,=11...

(-0.75)÷5/4÷(-0.3)=(-3/4)×4/5×(-10/3)=2
