32*2.5*12.5% 7/9*4/11+7/9/11/4 怎么做?要简算的...

32*2.5*12.5% =4×2.5×(8×12.5%) =10×1 =10 7/9*4/11+7/9/11/4 =7/9×(4/11+7/11) =7/9×1 =7/9

3.14*32*2.5*12.5简便运算/ 3.14*32*2.5*12.5 =3.14*(2.5*4)*(12.5*8) =3.14*10*100 =3140

(12.5*32*2.5×4×8)/(4×8)=1000

2.5×32 =2.5*4*8 =10*8 =80

=2.5x4x8x12.5

2.5*0.4*32 =(2.5*0.4)*32 =1*32 =32

仅次指标不需治疗。

①12.5×32×2.5=(12.5×8)×(4×2.5)=100×10=1000; ②6.8×9.9=6.8×(10-0.1)=6.8×10-6.8×0.1=68-0.68=67.32;③9.16×2.5-0.5×9.16=9.16×(2.5-0.5)=9.16×2=18.32; ④(1-0.2)÷(1-0.84)=0.8÷0.16=5.

0.125*32*2.5 =0.125*(8*4)*2.5 =0.125*8*(4*2.5) =1*10 =10

原式等于 2.5×4×(1.25×8) =10×10 =100 所以原式的计算结果为100.
