0.5*1.25*(4*8)=(0.5*4)*(1.25*8)=20 0.5*1.25*0.2*8=(0.5*0.2)*(1.25*8)=0.1*10=1 10.01*101-10.01=10.01*(101-1)=1001 4.6*3.1+3.1*5.4=3.1*(4.6+5.4)=31 0.8
1.25×67.875+125×6.7825+1.25×53.875=125×0.67875+125×6.7825+125×0.53875=125×(0.67875+6.7825+0.53875)=125*8=1000
你好,很高兴为你解答,答案如下:
1.25x3.3x0.8
=1.25x0.8x3.3
=1x3.3
=3.3
希望我的回答对你有帮助,满意请采纳。
8.88+3.7/1.25
=8.88+0.37*8
=8*(1.11+0.37)
=8*1.48
=11.84
1.25x32
=1.25x8x4
=10x4
=40
298+32+102-38
=298+102-38+32
=400-38+32
=362+32
=394
把原式写成以下形式
(100+1)x99-(900-3)
=9900+99-900+3
=9102
=783/125
=6又33/125
利用商不变性质给被除数和除数同时扩大8倍
8.9÷1.25
=(8.9×8)÷(1.25×8)
=71.2÷10
=7.12
