9.1×4.8×4又2分之1÷1.6÷20分之3÷1.3 要简便运算

9.1×4.8×4又2分之1÷1.6÷20分之3÷1.3 =(9.1÷1.3)×(4.8÷1.6)×(2分之9÷20分之3) =7×3×30 =630 供参考 有疑问请追问

9.1*4.8*7又二分之一÷1/4÷1.3÷1.6 =(9.1÷1.3)×(4.8÷1.6)×15/2×4 =7×3×30 =630

9.1÷4-3.1÷4 =(91.-3.1)÷4 =6÷4 =1.5

(9.1×9.4×1.9)÷(1.3×0.95×2.35)该怎样简算 =9.1x9.4x1.9÷1.3÷0.95÷2.35 =(9.1÷1.3)x(9.4÷2.35)x(1.9÷0.95) =7x4x2 =28x2 =56

(1)[11.4-(9.1× 6 7 +1.2)]÷1 3 5 +1÷0.25,=[11.4-(7.8+1.2)]÷1 3 5 +1÷0.25,=[11.4-9]÷1 3 5 +1÷0.25 =2.4÷1 3 5 +1÷0.25,=1.5+4,=5.5;(2)4 1 2 ÷[2 2 5 -( 3 4 ×1 1 3 +0.4)]-1.75,=4 1 2 ÷[2 2 5 -(1+0.4)]-1.75,=4 1 2 ...

(9.1×4.8×7.5)÷(0.25×1.3×1.6) =(9.1÷1.3)×(4.8÷1.6)×(7.5÷0.25) =7×3×30 =7×90 =630。

5.6÷0.7=8 8.8×0.1=0.88 1.07+1.3=2.37 9.1÷1.3=7 4×0.25=1 4.08÷8=0.51 0×9.9=0 1÷4=0.25 2.5×0.6=1.5 2.8-0.28=2.52 0.32÷0.4=0.8 80÷0.5=160

9.1x3.6x4又5分之4÷1又10分之3÷5分之3÷25分之6 =9.1x3.6x4.8÷1.3÷0.6÷0.24 =(9.1÷1.3)x(3.6÷0.6)x(4.8÷0.24) =7x6x20 =840
