5.5除以1.25能否巧算

5÷1.25-1.25÷5 =4-0.25 =3.75 你好,本题已解答,如果满意 请点右下角“采纳答案”。

5.5*1.25=11/2*5/4=55/8=6.875 1.25*3.5=5/4*7/2=35/8=4.375 1/0.8=1/4/5=5/4=1.25

15=(12.5+2.5)

24000除以1.25除以0.5除以2 =24000 ÷(1.25X0.5X0.2) =24X1000÷0.125 =24X8000 =192000

4.5x5+5.5÷0.2 =4.5x5+5.5x5 =(4.5+5.5)x5 =10x5 =50

1.6×2.5×1.25 =0.2×8×2.5×1.25 =(0.2×2.5)×(8×1.25 ) =0.5×10 =10

8.88×12.5 =(1.11x8)x12.5 =1.11x(8x12.5) =1.11x100 =111

5.27×9.5 +0.95×47.3 =5.27×9.5 +9.5×4.73 =9.5x(5.27+4.73) =9.5x10 =95 希望能帮到你!

1除以32除以0.125除以5巧算 =1/(8x0.125x4x5) =1/(1x20) =1/20 =0.05
