9.2X85,5.1X9.9十0.51,81.2÷39十1.8X2.1能简便就简便,不能简便,就不简便 9.2X85, =85*(10-0.8) =85*10-8.5*0.8 =782 5.1X9.9十0.51, =5.1*(99+1) =5.1*100 =510 81.2÷39十1.8X2.1 = 81.2÷39,结果不是有限小数,核实算式

(5/6-1/8)÷6/3÷6 =(5/6-1/8)×12 =10-3/2 =10-1.5 =8.5 (0.75-3/16)X(2/9+2/3) =(12/16-3/16)×(2/9+6/9) =9/16×8/9 =8/16 =2分之1 2/17*37÷15/17÷35/37 =2*15/37×37/35 =6/7 =7分之6 (18*11/23+5÷23/11)*60% =(18*11/23+5*11/23)*0.6 =11/2...

1÷1.25X0.8 =1/1.25×0.8 =4/5×0.8 =4/5×4/5 =16/25 祝你学习进步! 如有疑问请追问,理解请及时采纳!(*^__^*)

(5/8-1/4)x(8/9÷1又1/3)怎么算 =(5/8-2/8)x(8/9÷4/3) =3/8x2/3 =1/4

等等我来。

8.1×5.2+5.2×1.9 =5.2×(8.1+1.9) =5.2×10 =52

x-6.75=1.68 x=8.43 x÷2.8=5.6 x=15.68 1.2+1.2x=2.4 1.2x=1.2 x=1 4x-2.5=9.5 4x=12 x=3 0.7x+6×5=37 0.7x=7 x=10 1.2x-0.8x=4.8 0.4x=4.8 x=12
