8.0.37

3.7×0.8÷0.37 =3.7÷0.37×0.8 =10×0.8 =8

3.7×12.8+0.37×8.72 =3.7×12.8+3.7×87.2 =3.7×(12.8+87.2) =3.7×100 =370

0.72÷(3.33×0.8÷0.37) =0.72÷(9×0.8) =0.72÷7.2 =0.1

24.8×6.3-6.3×16.5 83x0.37 =6.3*(24.8-16.5)+83*0.37 =6.3*8.3+8.3*3.7 =8.3*(6.3+3.7) =8.3*10 =83

如图

3.7x12.8+0.37x872 =3.7x12.8+3.7x87.2 =3.7x(12.8+87.2) =3.7x100 =370

24.8x6.3-6.3x16.5+83x0.37 =6.3*(24.8-16.5)+83x0.37 =6.3*8.3+83*0.37 =8.3*(6.3+3.7) =83 满意采纳奥

24.8x6.3-6.3x16.5+ 83x0.37 =6.3x(24.8-16.5)+ 83x0.37 =6.3x8.3+ 83x0.37 =83x(0.63+0.37) =83x1 =83

7.8×0.37+0.78×6.3 =7.8×0.37+7.8×0.63 =7.8×(0.37+0.63) =7.8×1 =7.8
