下面各题简便计算过程1,(5/8+5/8)乘4/25 2,(5...

1、(5/8+5/8)乘4/25=10/8乘4/25=5/4乘4/25=1/5 2、(5/6-2/3)乘9/10=(5/6-4/6)乘4/6=1/9 3、1-7/9除7/8=9/9-7/9除7/8=16/63

(5/8+5/6)÷4/25 =(5/8+5/6)×25/4 =5/8×25/4+5/6×25/4 =125/32+125/24 =875/96 =9又11/96

(1)15.25+4.72+4.75+5.28=(15.25+4.75)+(4.72+5.28)=20+10=30(2)12.7-4.8-5.2=12.7-(4.8+5.2)=12.7-10=2.7(3)34.82-(4.82+15.2)=34.82-4.82-15.2=30-15.2=14.8(4)9.85+4.9-7.85=(9.85-7.85)+4.9=2+4.9=6.9(5)8.64-2.4+2.36-...

这样算吧 (4+0.8)×0.25=4×0.25+0.8×0.25=1.2 2.33×0.5×4=2.33×(0.5×4)=4.66 1.5×105=1.5×(100+5)=157.5

(1)原式=-8+10+6-4+8=12;(2)原式=-25-32+25-75=-2.9;(3)原式=-32-125×425-18÷9=-32-12-2=46;(4)原式=-8+1100×(-45)-8×14=-8-1125-2=-101125.

我用hi发给你

8分之3乘4分之3+8分之5乘75% =3/8*3/4+5/8*75/100 =9/32+15/32 =24/32 =3/4 (1+25%)除(1-25%) =125/100*100/75 =5/3 5除3分之4+3分之1 =5*3/4+1/3 =15/4+1/3 =45/12+4/12 =49/12

(1)4/(75%+50%-1) =4÷25% =16 (2)4.75*37.5%+8分之3*5.25 =4.75x3/8+5.25x3/8 =(4.75+5.25)x3/8 =10x3/8 =15/4 (3)5分之4×20%+5分之4 =4/5x(1+20%) =4/5x6/5 =24/25

432×2×125×25×5×4×8 =432×(125×8)×(25×4)×(5×2) =432×1000×100×10 =432000000

(1)9.9×25,=(10-0.1)×25,=10×25-0.1×25,=250-2.5,=247.5;(2)0.75×0.5×4×0.2,=(0.75×4)×(0.5×0.2),=3×0.1,=0.3;(3)1.25×32×0.25,=1.25×8×4×0.25,=(1.25×8)×(0.25×4),=10×1,=10;(4)8.12×4+1.88×4,=(8.12+1.88...
