脱式计算能简算的要简算 0.25x32x12.5 5分之2x68+0...

脱式计算能简算的要简算 0.25x32x12.5 =(0.25×4)×(8×12.5) =1×100 =100 2/5x68+0.4x32 =0.4×(68+32) =0.4×100 =40 14/5÷(14/5+7/10) =14/5÷7/2 =4/5 (2/3+4/15x5/6)÷10/21 =(2/3+2/9)÷10/21 =8/9÷10/21 =28/15 1-5/8÷25/28-3/10 =1-...

先算12.5*8=100*4.36=436 15.2/0.25/4=15.2*(0.25*4)=12.5

解答:解:0.77+0.33=1.1 7÷1.4=5 9+29=929 1-0.09=0.91 5656÷56=101 32÷53×0=031÷1000=0.031 2.6-1.7=0.9 23÷7=221 15×50=750 0.12×100=1 1-16+56=53

脱式计算能简算的要简算2.5×1.6×1.25 2.5×1.6×1.25 =2.5×2×0.8×1.25 =5×1 =5

12.5x(100+8)=12.5x12.5=156.25

①1375+450÷15×25,=1375+30×25,=1375+750,=2125;②137-(23+37),=137-23-37,=137-37-23,=1?23,=13;③43×99+43,=43×(99+1),=43×100,=4300;④(68-29×176)÷17,=(68-29×176)÷17,=(68-1727)×117,=68×117-1727×117,=4-127,=326...

1. 3.8+3.91÷(22-19.7) =3.8+3.91÷2.3 =3.8+1.7 =5.5 68÷[0.5x(7.5-0.7)] =68÷[0.5x6.8] =68÷0.5÷6.8 =68÷6.8÷0.5 =20 352-162÷36x24 =352-4.5x24 =352-108 =244 [六分之五-(十四分之五-七分之二)]x十八分之七 [5/6-(5/14-2/7)]x7/18 =(5/6-1/14...

0.25×32×12.5 =0.25×(4×8)×12.5 =(0.25×4)×(8×12.5) =1×100 =100

0.25x0.88 =0.25x4x0.22 =1x0.22 =0.22

4.05÷0.5+10.75 =8.1+10.75 =18.85 你好,本题已解答,如果满意 请点右下角“采纳答案”。
